True-rms Multimeter Introduction The Fluke Model 116, is a battery-powered, true-rms multimeter (hereafter "the Meter") with a 6000-count display and a bar graph. This meter meets CAT III IEC 61010-1 2nd Edition standards. The IEC 61010-1 2nd Edition safety standard defines four measurement categories (CAT I to IV) based on the magnitude of danger from transient impulses. CAT III meters are designed to protect against transients in fixed-equipment installations at the distribution level.
116 Users Manual Safety Information A "XWWarning" statement identifies hazardous conditions and actions that could cause bodily harm or death. A "WCaution" statement identifies conditions and actions that could damage the Meter or the equipment under test. To avoid possible electric shock or personal injury, follow these guidelines: • Use the Meter only as specified in this manual or the protection provided by the Meter might be impaired.
True-rms Multimeter Safety Information • • • • • • Comply with local and national safety requirements when working in hazardous locations. Use proper protective equipment, as required by local or national authorities when working in hazardous areas. Avoid working alone. Use only the replacement fuse specified or the protection may be impaired. Check the test leads for continuity before use. Do not use if the readings are high or noisy.

True-rms Multimeter Rotary Switch Positions Rotary Switch Positions Switch Position x e Hz (button) D l Ω s y R S $ Measurement Function Automatically selects ac or dc volts based on the sensed input with a low impedance input. AC voltage from 0.06 to 600 V. Frequency from 5 Hz to 50 kHz. DC voltage from 0.001 V to 600 V. AC voltage from 6.0 to 600 mV, dc-coupled. DC voltage from 0.1 to 600 mV. Ohms from 0.1 Ω to 40 MΩ. Continuity beeper turns on at <20 Ω and turns off at >250 Ω.
116 Users Manual Battery Saver ("Sleep Mode") The Meter automatically enters "Sleep mode" and blanks the display if there is no function change, range change or button press for 20 minutes. Pressing any button or turning the rotary switch awakens the Meter. To disable the Sleep mode, hold down the g button while turning the Meter on. The Sleep mode is always disabled in the MIN MAX AVG mode.
True-rms Multimeter Power-Up Options When you turn the Meter on, it defaults to Autorange and Auto is displayed. 1. To enter the Manual Range mode, press q. Manual is displayed. 2. In the Manual Range mode, press qto increment the range. After the highest range, the Meter wraps to the lowest range. Note You cannot manually change the range in the MIN MAX AVG or Display HOLD modes.
116 Users Manual Testing for Continuity Measuring Resistance eeo06f.eps XWWarning eeo04f.eps To avoid electric shock, injury, or damage to the Meter, disconnect circuit power and discharge all highvoltage capacitors before testing resistance, continuity, diodes, or capacitance. 10 Note The continuity function works best as a fast, convenient method to check for opens and shorts. For maximum accuracy in making resistance measurements, use the Meter’s resistance (e) function.
True-rms Multimeter Making Basic Measurements Measuring AC and DC Voltage Volts AC Measuring AC and DC Millivolts Volts DC V Millivolts AC Millivolts DC DC edy18f.eps eeo03f.eps Using Auto Volts Selection With the function switch in the x position, the Meter automatically selects a dc or ac voltage measurement based on the input applied between the + and COM jacks. With the function switch in the l position, the Meter measures ac plus dc millivolts. Press g to switch the Meter to dc millivolts.
116 Users Manual Measuring AC and DC Current WWarning To avoid personal injury or damage to the Meter: • • Never attempt to make an in-circuit current measurement when the opencircuit potential to earth is > 600 V. Use the proper switch position and range for your measurement. Flame sensor probe Control Module eeo08f.eps To measure flame rectification circuits: 1. Turn the function switch to $. 2. Connect the Meter between the flame sensor probe and the control module. 3.

116 Users Manual The Meter measures the frequency of a signal by counting the number of times the signal crosses a trigger level each second. The trigger level is 0 V for all ranges. Measuring Frequency XWWarning To avoid electrical shock, disregard the bar graph for frequencies >1 kHz. If the frequency of the measured signal is >1 kHz, the bar graph and Z are unspecified. AC Voltage Frequency Hz Hz V edy09f.eps 14 1. Press g to turn the frequency measurement function on and off.
True-rms Multimeter Making Low Impedance Capacitance Measurements Measuring Current above 600 μA Testing Diodes Good Diode The millivolt and voltage function of the Meter can be used with an optional mV/A output Current Probe to measure currents that exceed the rating of the Meter. Make sure the Meter has the correct function, AC or DC, selected for your current probe. Refer to a Fluke catalog or contact your local Fluke representative for compatible current clamps.
116 Users Manual Using the Bargraph The bar graph is like the needle on an analog meter. It has an overload indicator (>) to the right and a polarity indicator (+) to the left. Maintenance Maintenance of the Meter consists of replacing the battery and cleaning the case. Because the bar graph updates much faster than the digital display, the bar graph is useful for making peak and null adjustments. Replacing the Battery The bar graph is disabled when measuring capacitance and temperature.
True-rms Multimeter Cleaning XWWarning To avoid shock, injury, or damage to the Meter, remove test leads from the Meter before opening the case or battery door. To remove the battery door for battery replacement: 1. Remove the test leads from the Meter. 2. Remove the battery door screw. 3. Use the finger recess to lift the door slightly. 4. Lift the door straight up to separate it from the case.
