Test inhibit
Each test mode has conditions under which testing will be inhibited, as below:
Insulation
Detection of a circuit voltage above 50 V (a warning is displayed at 25 V).
Continuity
Detection of a circuit voltage above that used by the instrument will inhibit testing.
GFCI testing
Touch voltage detected or predicted to exceed 50 V (or 25 V depending on instrument configuration).
Supply voltage over range or under range.
Supply Frequency out of specification.
Ground testing
External voltage greater than 25 V present.
Leads not connected as per the test requirements.
Potential stake not within range (Rp).
Current stake not within range (Rc).
Other conditions that will inhibit testing include:
Battery exhausted
All testing will be inhibited in the event of a flat battery, refer to “Battery and fuse location, fitting and
replacement” on page 10.
