9.10 Inrush Current Measurements
In Inrush Current mode, the meter displays the AC RMS current reading in the first 100ms
period after the trigger point (current detection threshold) is reached, see Fig. 9-3 below.
For the FLEX Current function:
Current detection threshold is 0.5A for 30.00A
Current detection threshold is 5A for 300.0A
Current detection threshold is 50A for 3000A
For CLAMP Current function:
Current detection threshold is 0.5A for 60.00A
Current detection threshold is 5A for 600.0A
Inrush current mode is available when measuring AC current.
1. Press OK to access the main menu
2. Press OK at the Advanced Menu icon
3. Press OK at the Inrush Current icon , the Inrush display icon will appear
4. Connect the meter to the unpowered circuit under test
5. Set the meter to the position
6. Turn on the power to the circuit under test
7. When it reaches the threshold, the meter will display the RMS reading for the
100ms integration time.
