FLIR Systems reserves the right to discontinue models, parts or accessories, and other items, or to change specifications at any time without prior notice. Remove the batteries if the device is not used for an extended period of time. Warning Statements To ensure the safe operation and service of the meter, follow these instructions closely.
CAUTIONS CAUTIONS identify conditions and actions that could cause DAMAGE to the meter or equipment under test. Do not expose the meter to extremes in temperature or high humidity. Safety Symbols that are typically marked on meters and instructions This symbol, adjacent to another symbol, indicates the user must refer to the manual for further information.
3. Introduction Thank you for choosing the FLIR TA72 or TA7 4 UNIVERSAL FLEX CURRENT PROBE ACCESSORY that can measure up to 3000A AC. A standard Digital MultiMeter (DMM) in VAC mode can be used to display the current measurement when the current probe is connected to the DMM. The TA74 is the 18” (45.7cm) clamp version and the TA72 is the 10” (25.4cm) clamp version, otherwise both meters are the same. These devices are professional CAT IV 600V CAT III 1000V instruments with high power Work Lights.

5. Operation Note: Before operating the device, please read and understand all Warning and Caution statements and follow all instructions and notes. Note: Models TA72 and TA74 are not designed for use with VFD (Variable Frequency Drive) equipment, as erroneous readings may result. Using with VFD equipment does not pose a safety hazard to personnel and will not damage equipment. Please contact FLIR for additional information. 5.1 Powering the Meter The meter is powered by two (2) AAA 1.
5.3 AC Current Measurements WARNING: Ensure that power to the device under test is OFF before starting this procedure. Switch power to the device under test ON only after the clamp has been safely attached to the device under test. CAUTION: Do not move fingers above the range lamps at any time during a test. Note: Models TA72 and TA74 are not designed for use with VFD (Variable Frequency Drive) equipment, as erroneous readings may result.
7. Attach the flexible clamp coil tip (2) to the lock (1) and lock it in place by turning the clamp lock clockwise. See Fig. 5‐2. 8. Switch the Clamp Adaptor ON (press and hold the Power button) and then switch the device under test ON. Never move fingers higher than the range indicator lights when testing. Keep hands and fingers away from the clamp coil while testing. 9. Read the current value in the DMM display. Refer to Sections 5.3.1 to 5.3.
5.3.2 DMM Reading Multiplier Table The Table below uses FLIR DM93 and CM83 DMMs as examples; However, most standard DMMs set to the AC Voltage mode will respond similarly. Note: Do not set the DMM to VFD mode when testing.

6. Maintenance 6.1 Cleaning and Storage Clean the meter with a damp cloth and mild detergent; do not use abrasives or solvents. If the meter is not to be used for an extended period, remove the batteries and store them separately. 6.2 Battery Replacement CAUTION: Disconnect the meter from the conductor under test and switch the meter OFF before opening the battery compartment. 1. Remove the battery compartment Phillips head screw from the back of the meter. 2. Remove the battery compartment cover. 3.
