FieldMaxII-TO User Manual Left Side Panel The left side panel contains the Analog Out and Power Jack connectors (refer to Figure 5). Analog Out Connector Power Jack Connector Figure 5. Left Side Panel Analog Out Connector When power is on, the Analog Out connector outputs a voltage proportional to the current laser measurement. The output voltage is zero (0) volts when the measured power is zero (0) or less.
Description Battery Replacement FieldMaxII-TO uses six 1.5V alkaline batteries, or a 90-to-260 VAC, 50/60 Hz AC adapter (refer to “AC Adapter” on page 16 for more information). Figure 6 illustrates how to replace the batteries. An optional rechargeable battery pack is also available for FieldMaxII-TO. Visit our website (www.Coherent.com), or contact a Coherent representative for more information (see Table 3, “Coherent Service Centers,” on page 76 for contact information). Figure 6.
FieldMaxII-TO User Manual AC Adapter Using an AC adapter prolongs battery life. FieldMaxII-TO automatically senses when an adapter is used. When batteries rather than an adapter, are used, the Battery annunciator flashes if the battery charge is low. While in battery operation, if a sensor is not connected to the meter, power is automatically turned off after ten minutes.
Operation OPERATION This section discusses the following topics: • Tuning mode (page 18) • Annunciators (page 22) • Fault displays (page 25) • Invalid and not available data conditions (page 26) • Setup parameters (page 27) • Button functions (page 33) • Statistics mode (page 35) • Measurement (page 36) 17 display and range selection
FieldMaxII-TO User Manual Tuning Mode This mode only works in Manual Ranging mode. For more information about ranging, refer to “Auto vs. Manual Ranging Mode” on page 39. As shown in Figure 7, tuning is visually displayed on the LCD using tuning needles and zone indicator bars. Tuning Needles Zone Indicator Bars Figure 7.
Operation Tuning Needles Tuning needles—which divide a given tuning zone into thirty “increments”—are used to peak a laser output. As the top or bottom of a zone is reached, the tuning needles automatically move to the center of the next zone (see Figure 8). Zone indicator bars let you know when this happens (refer to “Zone Indicator Bars” on page 20 for more information). Mid-Range of Current Scale Figure 8.
FieldMaxII-TO User Manual Zone Indicator Bars Zone indicator bars are a series of six segments, as shown in Figure 9: Zone Indicator Bars Figure 9. Zone Indicator Bars These bars act as visual indicators while the tuning needles automatically move through zones, and also provide a relative indication of where the measurement falls within the active range.
Operation Zone indicator bars always appear in pairs, with each overlapping zone representing 1/3 of full scale. Figure 10 shows how the five zone indicator bars correlate to full scale measurement on the tuning meter scale. Figure 10.
FieldMaxII-TO User Manual Figure 11 shows an example of how the zone indicator bars overlap on a 30-watt scale: Figure 11. Tuning Mode Example - Full Scale Annunciators Annunciators refers to the icon-type symbols that appear on the LCD (Figure 3 on page 11 shows all the annunciators on the FieldMaxII-TO meter). The update rate for all annunciators is 3 times per second.
Operation Range Hint The Range Hint annunciator—towards the top of the LCD, just above the tuning needles—displays “3,” “30,” or “300.” These numbers represent the full-scale range currently selected by the user. Range Hint is discussed in more detail under “Measurement Display and Range Selection” on page 36. AVG When AVG (display smoothing) is active, display values are averaged by time. “AVG” displays when averaging is active. Nothing displays in this position if averaging is not active.
FieldMaxII-TO User Manual Hold The Hold annunciator toggles between freezing the power reading and associated indicators on the LCD, and displaying live measurements.
Operation Fault Displays FieldMaxII-TO is capable of detecting internal and userinduced faults. When a fault is detected, the letters “Er”—followed by a numeric fault code (see Table 1)—appear on the display. You can dismiss a fault code by pressing any button, or by correcting the cause of the fault. Table 1.
FieldMaxII-TO User Manual As an example, “Er 4” appears on the display if there is a sensor error. You can dismiss the fault by removing the sensor from the meter, or by pressing any button. Attaching an unrecognized sensor to the meter creates a special fault condition. This condition is characterized by displaying a sensor fault (1 through 5). Invalid and Not Available Data Conditions The update rate for invalid or not available data conditions is three times per second.
Operation Setup Parameters This section explains how to select and set user-definable parameters. Setup/Local The Setup/Local button serves several purposes: 1. If an edit cycle is not in progress, pressing the Setup/Local button initiates an edit cycle. If the next button pressed represents an edit parameter (STAT, WAVE, AREA, ATTEN, or AVG button), Edit mode is entered and the parameter for the applicable button may be edited using the edit buttons.
FieldMaxII-TO User Manual 4. Setup/Local is used to cancel the front panel lockout when Remote Control is active. Remote Control is active when the instrument is connected to a host computer via a USB connection and is communicating with a host application program. While the instrument is in Remote Control mode, all front panel buttons—except Power/Backlight and Setup/Local—are disabled.
Operation Stat Wave Pressing the Stat button will: • Enter Statistics mode—if Statistics mode is not active and the button is pressed for less than two seconds. • Exit Statistics mode. • Enter Edit mode and select the statistics parameters to be edited (Batch Size and Restart mode) after edit cycle initiation (if Setup/Local is pressed beforehand). Batch size is 1 to 99,999 seconds. • View the statistics parameters if the button is pressed for two seconds or more.
FieldMaxII-TO User Manual display the wavelength value. The available wavelength range is 1.00 to 99,999 nm. The actual range is sensordependent. If Wavelength compensation information is not programmed into the sensor, you will not be able to change the wavelength data value. Area This mode allows the measurement of laser power in terms of average power density. Area calculation returns an average power density reading for both Flat and Gaussian profiles.
Operation Area Correction and Zeroing It is important that you zero the sensor before using Area Correction, as explained in the following procedure. 1. Enter Area Correction by pressing the Area button for less than one second. 2. Set Auto Ranging by pressing the Auto button. 3. Block the sensor beam. 4. Allow the sensor to enter a steady (cool-down) state. If you are using a thermopile sensor, this steady state can be determined by watching the display numbers on the LCD.
FieldMaxII-TO User Manual The FieldMaxII-TO uses a boxcar averaging method, with a boxcar length of 32 samples. Pressing the Avg button toggles the state of Average mode. Atten Attenuation mode allows you to get true measurements using an attenuator that has a known attenuation factor. When Attenuation Correction mode is enabled, the measured value is adjusted to indicate the measurement at the attenuator and not the sensor. The range for this mode is 0.01 to 999.99.
Operation Hold Pressing the Hold button toggles between freezing the power reading and associated indicators on the LCD, and displaying live measurements. Button Functions Auto Pressing the Auto button instructs the FieldMaxII-TO to select the best measurement range for the incoming signal. Zero Pressing the Zero button causes the analog circuitry to zero its internal settings by running a zero cycle. If Auto Ranging is not active, the meter will zero the currentlyselected range.
FieldMaxII-TO User Manual • Select a new range • Press the Zero button The secondary function of the Zero button is to manually start a batch while in Statistics mode. Power Switch and Backlight Toggle Button Up and Down Arrows The combination Power Switch and Backlight Toggle button serves the dual purpose of turning power on/off to the meter, and toggling the backlight. • When the meter is off, the power-on state is activated by pressing the button for one second.
Operation Left and Right Arrows This button pair has a dual purpose. When the Edit mode is active, the buttons allow you to select the edit field of the currently-selected edit parameter. When the Edit mode is not active and Statistics mode is active, the buttons are used to select the statistical parameter of interest (MAX, MIN, or MEAN). These buttons are nonfunctional when Edit mode and Statistics mode are not active.
FieldMaxII-TO User Manual result computed. If the Restart mode is Auto, a new batch is immediately restarted. The error that caused the contaminated batch is displayed. Measurement Display and Range Selection The display update rate for numeric measurement is three times per second. Measurement range is selected in decade steps. Range selection (shown in Table 2 on page 37) is dependent on the sensor type and characteristics, as well as user-determined measurement settings.
Operation Over-ranging refers to a meter setup condition in which the sensor output signal is greater than the maximum allowable level for the selected range. An “OL” (overload) appearing on the display signifies an over-range condition. Over-ranging generates invalid data. When area correction is enabled in Watts mode, a “/cm2” will be appended to the units. Table 2 indicates the display format for different fullscale range settings. Table 2.
FieldMaxII-TO User Manual Table 2. Full Scale Range Settings (Continued) FULL SCALE MEASUREMENT DISPLAY FORMAT 300 W XXX.Y W 3 kW X.YYY kW 300 kW XX.YY kW The Range Hint annunciator displays the full-scale range value with the engineering prefix and units omitted. For example, when the range is 30 kW, the Range Hint annunciator displays “30.” Note that it also displays “30” when the selected range is 30 W, 30 mW, 30 µW, or 30 nW.
Operation Auto vs. Manual Ranging Mode Auto Ranging (Auto) enables FieldMaxII-TO to automatically select the range (gain). While in Auto Ranging mode, the tuning needles represent a zero-to-full scale movement (as compared to Tuning mode, where the zones overlap). Refer to Figure 12. Tuning Needles Figure 12. Auto Ranging Manual ranging requires the range to be selected by the user. For more information, refer to “Up and Down Arrows” on page 34.
FieldMaxII-TO User Manual active, the sensor is zeroed at the current range only. Under typical operating conditions, the zero procedure takes about one second for each range. When starting the zeroing procedure, the large numerals on the LCD are replaced by an animated set of dashes. Unless there is an error, the normal measurement mode resumes once the zeroing procedure ends.
Special Topics SPECIAL TOPICS This section discusses the following topics: Negative Power Display • Negative power display (this page) • Digital tuning feature use in Statistics mode (this page) • ActiveX installation (page 42) • USB driver installation (page 42) A negative power reading indicates the sensor needs to be zeroed. Two areas of the display are affected by a negative power reading: the digital tuning feature and the numeric measurement display.
