SETUP MODE The advanced Setup Mode allows you to customize the following meter preferences and defaults: Real Time Clock Decimal Type Auto Power Off Touch-Tone Thermometer Type K/J Temperature Units Sampling Time SD Memory Card Format Note… The setup functions can be performed under any parameter but not while utilizing the datalogger function. Once selections are saved, the meter will default to the selected preferences when the meter is turned off and on again.
SETUP MODE Real Time Clock 1. Enter the clock function from Setup Mode (see page 10). “dAtE” appears on the LCD. 2. Press ENTER. The year will appear on the LCD. 3. Press ▲ or ▼ to adjust the value. Press ENTER to save the value. 4. Repeat Step 3 to adjust the month, date, hour, minute and second. Note… This procedure adjusts the meter’s internal clock. The internal clock will function when the meter is turned off but only when the batteries have adequate power (not with low battery power.
SETUP MODE Auto Power Off The meter automatically turns off after 10 minutes of inactivity, however this function can be disabled. 1. Enter the auto power off function from Setup Mode (see page 10). “PoFF” appears on the LCD. 2. Press ▲ or ▼ to select yes (auto power off enabled) or no (auto power off disabled). Press ENTER to save the selection. Touch-Tone 1. Enter the touch-tone function from Setup Mode (see page 10). “bEEP” appears on the LCD. 2.
SETUP MODE 2. Press ▲ or ▼ to select C (degrees Celcius) or F (degrees Fahrenheit). Press ENTER to save the selection. Sampling Time The sampling time is the time allotted between successive measurements. To adjust the sampling time (in seconds): 1. Enter the sampling time function from Setup Mode (see page 10). “SP-t” appears on the LCD. 2. Press ▲ or ▼ to adjust the value (0, 1, 2, 5, 10, 30, 60, 120, 300, 600, 800, 1800, 3600 seconds). Press ENTER to save the value.
MEASUREMENT PROCEDURES Turning the Unit On/Off 1. Press POWER to turn the meter on. 2. Press and hold POWER for 2 seconds to turn the meter off. Selecting the Function 1. Press and hold FUNC to cycle through the options listed below. Release FUNC when you reach the desired function. Air velocity/temperature: “An” appears on the LCD. Type K/J thermometer: “tP” appears on the LCD. Note… The meter will default to the last function setting used when it is turned off and on again.
MEASUREMENT PROCEDURES Air Velocity and Air Temperature When the probe is not used, the sensor cover should be in the up position. Probe Handle Direction mark Air velocity sensor Sensor cover slides down when using the probe. 1. Press POWER to turn the meter on. 2. Plug the anemometer probe plug into the anemometer probe input socket. 3. Press and hold FUNC to cycle through the options until “An” appears on the LCD. Release the FUNC button. 4.
MEASUREMENT PROCEDURES Type K/J Thermometer 1. Press POWER to turn the meter on. 2. Press and hold FUNC to cycle through the options until “tP” appears on the LCD. Release the FUNC button. 3. The anemometer probe must be disconnected from the meter to obtain accurate Type K/J readings. 4. Plug a thermocouple temperature probe (type K or J) into the type K/J thermometer socket. The LCD will display the measurement value from the temperature probe. 5.
MEASUREMENT PROCEDURES Maximum and Minimum To record maximum and minimum readings: 1. When measuring any parameter, press REC to begin recording the maximum and minimum values. “REC” appears on the LCD. 2. Press REC. The maximum value and “REC MAX” will appear on the LCD. 3. Press REC. The minimum value and “REC MIN” will appear on the LCD. 4. To delete the maximum or minimum value, press HOLD. “REC” appears on the LCD and the meter will begin recording the maximum and minimum values again. 5.
MEASUREMENT PROCEDURES Backlight 1. The backlight turns on automatically when the meter is turned on. 2. Press to turn the backlight off. 3. Press to turn the backlight on. View Real Time Clock To view the time function during normal measurement (not during datalogging): 1. Press TIME CHECK. The time information (Year, Month/Date, Hour/Minute) will appear on the lower display of the LCD. View Sampling Time To view the sampling time function during normal measurement (not during datalogging): 1.
DATALOGGER Preparing the Datalogger 1. Insert the SD card into the SD card socket on the bottom of the meter, ensuring that the front of the SD card faces the back of the meter. 2. Format the SD card as needed (see page 13). 3. Set the real time clock if using the meter for the first time (see page 11). 4. Set the decimal type if using the meter for the first time (see page 11). Auto Datalogging 1. Set the sampling time to ≥ 1 second (see page 13). 2. Press REC. “REC” will appear on the LCD. 3.

DATALOGGER SD Card Data Structure 1. The first time a SD card is used in this meter, a folder AMA01 will be generated. 2. If the datalogger is being used for the first time, a new file AMA01001.XLS will be generated under the route AMA01\. After exiting the datalogger and executing the function again, the data is saved to the AMA01001.XLS file until the data reach 30,000 data columns. A new file will then be generated (i.e., AMA01002.XLS). 3. The folder AMA01\ will hold 99 files. A new route (i.e.
BATTERY REPLACEMENT This meter uses six AA (1.5 V, UM3) batteries. When the low battery indicator appears on the LCD, battery replacement is needed. After the icon appears on the LCD, in-spec measurement can still be made for several hours before becoming inaccurate. 1. Press POWER to turn the meter off. 2. Unscrew the battery cover and remove from the meter. 3. Remove the old batteries and replace with six new AA batteries, ensuring correct polarity. 4. Replace the battery cover.
