press the lock or test button again to release the lock.
J. Range/Test Voltage/Temperature Scale Button:
• Press and hold to return to Auto Ranging mode
• Press to select desired voltage source in Insulation Resistance mode.
• Press to select °F or °C in Temperature mode.
K. PI/DAR/Hz (Polarization Index/Dielectric Absorption Ratio) Button: Use PI for test of insulation deterioration
and DAR for extended insulation resistance test.
• Press x1 for PI mode.
• Press x2 for DAR mode.
• Press for Hz/Frequency measurement in AC Volts mode and AC mA mode.
L. Test Button: Initiate test function
M. Protective Rubber Boot: With molded comfortable grip.
N. Test Lead Holders: For hand-free use and storage of the test probes.
O. Kick Stand: For easy viewing of screen when testing.
P. Battery and Fuse Cover (under protective rubber boot)
