5. Operation Note: Before operating the device, please read and understand all Warning and Caution statements and follow all instructions and notes. 5.1 Powering the Meter The meter is powered by two (2) AAA 1.5V batteries (located in the compartment on the back of for > 2 seconds to switch the device ON or OFF. the meter). Press and hold the Power button 5.1.1 Auto Power OFF (APO) The meter switches OFF automatically after an approximately 10‐minute period of inactivity.
5.4 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 LCD at any time during a test. 1. 2. 3. 4. 5. 6. 7. 8. Switch the meter OFF and switch power to the device under test OFF. Turn the clamp lock (1) counter‐clockwise to release the flexible clamp (2).
5.4.1 Inrush Current mode The meter has the ability to capture an inrush current signal using a 100ms sampling window. The sampling window opens only when the threshold current (see below) is detected. When detecting an input current ±50 digits of the selected range the meter will calculate the RMS values for a 100mS period and display this value. Refer to illustration below. For the 30A range the minimum triggering current threshold is 0.
5.5 Data Recording and Bluetooth® Data Transfer 5.5.1 Data Recording When prompted, this meter can store readings into its internal memory automatically for later transfer over Bluetooth® (real‐time data streaming over Bluetooth® is also possible as explained below) using the FLIR TOOLS application. The maximum number of records that can be stored is 20,000 and the fixed sampling (recording) interval is 1 minute. 1. Press the REC button >2 seconds to enter the Data Record Mode.
5.5.3 Transferring Recorded Readings with Bluetooth® To transfer bulk logged readings from the meter’s internal memory to a Bluetooth® paired device running the FLIR TOOLS application please read the steps below. Note that the Bluetooth range is 32’ (10m) maximum. 1. Press and hold the Bluetooth button 2. 3. 4. Press and hold the SEND button until the percent (%) symbol appears The data is now being transmitted. The percentage shown is the percentage of data transmitted.
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: Remove the meter from the conductor under test and switch the meter OFF before opening the battery compartment. 1. With a Phillips screwdriver, remove the battery compartment screw on the back of the meter. 2.
