*Because of the method used to measure resistance, the 100 M
Ω
(slow) and 300 M
Ω
(medium and fast)
ranges cannot measure below 3.2 M
Ω
and 20 M
Ω
, respectively. "UL" (underload) is shown on the display for
resistances below these nominal points, and the computer interface outputs "+1 E-9".

Test Current
Approximately 0.7 mA when measuring a forward biased junction.
Audible Tone
Continuous tone for continuity. Brief tone for normal forward biased diode or
semiconductor junction.
