2. Accuracy is speciied after applying the Relative function to offset any test lead resistance and thermal effect.
3. Accuracy is speciied for < 60% R.H.
Overload protection
250 Vrms
Diode and continuity speciications
For diode test, the overload protection is 250 Vrms and the instrument will beep when the reading is below 50 mV (approximately). For
continuity test, the instrument will beep when the resistance is less than 10.00 Ω.
