2 Safety information WARNING Do not measure the current on a circuit when the voltage increases to more than 600 V. This can cause damage to the instrument and can cause injury to persons. WARNING You must disconnect the test leads from the circuit that you did a test on be- fore you change the range.
Page 10
2 Safety information WARNING Be careful when you do the measurements if the voltages are more than 25 VAC rms or 35 VDC. There is a risk of shock from these voltages. Injury to per- sons can occur. WARNING Do not do diode, resistance or continuity tests before you have removed the power from capacitors and other devices under test during a measurement.
2 Safety information WARNING Do not cause a short-circuit of the batteries. This can cause damage to the in- strument and can cause injury to persons. WARNING Do not put the batteries into a fire. Injury to persons can occur. CAUTION Do not use the device for a procedure that it is not made for.
2 Safety information and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be deter- mined by turning the equipment off and on, the user is encouraged to try to cor- rect the interference by one or more of the following measures: •...
3 Introduction Congratulations on your purchase of the FLIR CM78 True RMS Clamp/DMM with infrared thermometer and Bluetooth METERLiNK®. This meter is supplied in the METERLiNK® kit and includes a Bluetooth module designed for use with FLIR infrared cameras. The combination of a clamp meter and an infrared (IR) camera is used for electrical power measurement, analysis, and documentation.

4 Description Figure 4.2 Rear view IR sensor. Laser pointer diode. Battery compartment. 4.2 Function switch The meter can measure voltage or frequency through the probe inputs. The type of measurement is selected by the button. The meter can measure resistance, continuity, or diode polarity through the probe inputs.
4 Description The meter can measure DC current through the clamp jaws. The meter can measure AC current through the clamp jaws. The meter can measure temperature through the thermocouple inputs. The meter can measure IR temperature through the IR sensor. The meter is in full power-saving mode 4.3 Function buttons Press the button to change the operating mode for the currently...
4 Description Press the button to toggle between Normal and Hold mode. In Hold mode, the display freezes the last reading and continues to display this value. Press the button to enable/disable METERLiNK® (Bluetooth) communication, see section . 4.4 Display icons and indicators Figure 4.3 Display Indicates that METERLiNK®...

4 Description Indicates that the meter is in Hold mode. Indicates the battery voltage status. Indicates that the meter is measuring AC current or voltage. Indicates that the meter is measuring DC current or voltage. Indicates that the continuity function is active. Indicates that the diode test function is active.
5 Operation Note Before operating the device, you must read, understand, and follow all in- structions, dangers, warnings, cautions, and notes. Note When the meter is not in use, the function switch should be set to the position. Note When connecting the probe leads to the device under test, connect the nega- tive lead before connecting the positive lead.
5 Operation To enter Manual range mode, press the button. To change the range, press the button repeatedly until the desired range is displayed. To return to Auto range mode, press and hold the button until the indi- cator is displayed. 5.3 Current measurements When measuring current using the clamp jaws, only one conductor should be en- closed by the jaws—refer to Figure 5.1.
5 Operation Note The meter can also be set to display peak values only, see section 5.13 Peak hold, page 20. 5.3.1 DC Zero The DC Zero feature removes offset values and improves the accuracy of DC current measurements. Set the function switch to the position.
5 Operation 5.5 Resistance measurements WARNING Do not do diode, resistance or continuity tests before you have removed the power from capacitors and other devices under test during a measurement. Injury to persons can occur. Set the function switch to the position.
5 Operation Note For very large capacitance values, it may take several minutes for the meas- urement to settle and the final reading to stabilize. 5.7 Frequency measurements Set the function switch to the position. Insert the black probe lead into the negative COM terminal and the red probe lead into the positive V terminal.
5 Operation Insert the black probe lead into the negative COM terminal and the red probe lead into the positive Ω terminal. Use the button to select continuity measurement. The indicator should be displayed. Touch the tips of the probe across the circuit or component under test. If the resistance is less than 30 Ω, the meter beeps continuously.

5 Operation from the target, the diameter (spot) of the object under test must be at least 1 inch (2.54 cm). Refer to Figure 5.2. Figure 5.2 IR spot-to-distance ratio IR measurement notes: • The object under test should be larger than the size of the laser beam spot. •...
5 Operation WARNING Do not use the laser pointer near explosive gases or in other possible explo- sive areas. Injury to persons can occur. Set the function switch to the position. Press and hold the button to enable the IR sensor and the laser pointer diode.
5.15 Streaming measurement data using Bluetooth 5.15.1 General Some IR cameras from FLIR Systems support Bluetooth communication, and to those cameras you can stream measurement data from the meter. The data is then merged into the result table in the IR image.
Page 28
5 Operation 5.15.2 Procedure Pair the IR camera with the instrument. Refer to the camera manual for infor- mation on how to pair Bluetooth devices. Turn on the camera. Turn on the meter. Press the on the meter to enable Bluetooth. Choose the variable that you want to use (voltage, current, resistance, etc.).
As with most electronic products, this equipment must be disposed of in an envi- ronmentally friendly way, and in accordance with existing regulations for elec- tronic waste. Please contact your FLIR Systems representative for more details. #T559826; r. AD/ 9130/9130; en-US...
