Failure to observe warnings can result in severe injury. WARNINGS identify hazardous conditions and actions that could cause BODILY HARM or DEATH. Individual protective equipment should be used if HAZARDOUS LIVE parts in the installation where measurements are to be carried out could be accessible. If the equipment is used in a manner not specified by the manufacturer, the protection provided by the equipment may be impaired. Always use proper terminals, switch position, and range for measurements. To reduce the risk of fire or electric shock, do not expose this product to rain or moisture. Verify the meter operation by measuring a known current. If in doubt, have the meter serviced. Do not apply more than the rated voltage/current as marked on the meter. To avoid false readings that can lead to electric shock and injury, replace battery as soon as the low battery indicator appears. Do not use the meter in or around explosive gas or vapor. Do not use a flexible current sensor if the inner copper wire of the flexible cord is visible. ...

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. This meter is shipped fully tested and calibrated and, with proper use, will provide years of reliable service. 3.1 Key Features 3000A AC Current Measurements displayed on connected DMM Convenient Flexible Clamp with locking mechanism 0.3” (7.5mm) coil diameter for measuring in tight spaces Supplied banana plug cables Power button Battery status LED indicator Current AC Range select switch 30A, 300A, 3000A Battery powered High power work lights Register for Extended Warranty www.Flir.com/testwarranty FLIR TA72_TA74 USER MANUAL Document Identifier: TA72_TA74 en‐US_AC ...

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 1.5V batteries (located in the compartment on the back of the meter). Press and hold the Power button for > 2 seconds to switch the device ON or OFF. The meter will beep as it switches ON and one of the Range indicator lamps will be lit. Use the Range button to select a range manually. If the meter does not switch ON please check the batteries located in the rear battery compartment. Refer to the battery replacement section of this User Guide. 5.1.1 Auto Power OFF (APO) The meter switches OFF automatically after an approximately 10‐minute period of inactivity. Several seconds before the meter automatically switches OFF the meter beeps several times to alert the user. To disable the APO feature, press both the RANGE and POWER buttons simultaneously (with the meter OFF). The three range indicator LEDs will flash three times. To re‐enable APO, turn the meter OFF then ON. The meter re‐enables APO each time the meter is powered OFF. 5.2 Work Lights With the unit powered up, press the Work Light button to switch the high power Work Lights ON or OFF. Note that excessive use of the Work Lights will shorten battery life. FLIR TA72_TA74 USER MANUAL Document Identifier: TA72_TA74 en‐US_AC ...
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. Using with VFD equipment does not pose a safety hazard to personnel and will not damage equipment. Please contact FLIR for additional information. Switch OFF the Clamp Adaptor, the DMM, and the device under test. Connect the Clamp Adaptor to the DMM input jacks using the supplied banana plugs (Fig. 5‐1). V AC Switch ON the DMM and set the DMM to the AC V mode. Use the RANGE button to set the measurement Fig. 5‐1 Connect to DMM range of the Clamp Adaptor to the expected current range measurement. Turn the clamp lock (1) counter‐clockwise to release the clamp (2). See Fig. 5‐2. Fully enclose the conductor under test with the flexible clamp probe (see Fig. 5‐3). Do not measure current higher than the specified current limit. Fig. 5‐2 Clamp Jaw Lock FLIR TA72_TA74 USER MANUAL Document Identifier: TA72_TA74 en‐US_AC ...
