*Because of the method used to measure resistance, the 100 MΩ (slow) and 300 MΩ (medium and fast)
ranges cannot measure below 3.2 MΩ and 20 MΩ, respectively. "UL" (underload) is shown on the display for
resistances below these nominal points, and the computer interface outputs "+1 E-9".
Open Circuit Voltage
3.2 V maximum on the 100 Ω, 300 Ω, 30 MΩ, 100 MΩ, and 300 MΩ ranges, 1.5 V
maximum on all other ranges.
Input Protection
500 V dc or rms ac on all ranges

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.
