Warning Icons
This section details the warning icons that can show on the display.
Icon Warning Description
F
External Voltage Warning If an external voltage is applied between the terminals and the
instrument is set to On, the High Voltage warning will flash on the
display. This is a warning that the item under test is live and might be
dangerous and testing is disabled. The High Voltage warning message
will flash if more than 50 V potential difference is applied between
the Voltage terminals and the Current terminals. This warning will not
show if all terminals are at the same high voltage.
Note: The warning will not operate if the instrument is set to Off.
F
Discharge Voltage /
Current Warning
The High Voltage warning and the red High Voltage LED on the panel
will flash if a current greater than 1 mA is still flowing after an inductive
test is completed. This suggests that the inductive load has been
tested and is discharging. Do not disconnect the current loop while the
discharge warning is showing.
