Continuity
[10]
500.00 Ω 0.01 Ω 1.04 mA 0.05 + 10
Notes for continuity specifications:
10 Instant continuity: built-in beeper will sound when resistance is less than 10.0 Ω.
Diode
[11][12][13]
3.0000 V 0.1 mV 1.04 mA 0.05 + 5
Notes for diode specifications:
a 2% over-range on all ranges except DC 1000 V range.
11 Built-in beeper will sound when the reading is below approximately 50 mV. Also, single-tone beeping for normal
forward-biased diode or semiconductor junction with bias voltage between 0.3 V and 0.8 V.
12 These specifications are defined for voltages measured at the input terminals only. The test current is typical. Variation in
the current source will create some variation in voltage drop across a diode junction.
13 Maximum open voltage: < + 4.2 V.
