Electrical Speciﬁcations

Accuracy

± (% reading + number of digits) at 23 °C ± 5 °C at < 80 % R.H.

Temperature Coefﬁcient

Add 0.2 x (Speciﬁed Accuracy) / °C, < 18 °C, > 28 °C

Voltage

Function Range Accuracy

V  1.3 V to 750.0 V

±(1.5% + 3 dgts)

50 Hz – 500 Hz

V 

2.1 V to 1000 V ±(1% + 2 dgts)

-0.7 V to 1000 V ±(1% + 4 dgts)

Overload Protection: 1000 VDC / 750 VAC

Max Operation Time: DT = 30s for ≥ 30 V

Input Impedance: ≥ 4 kΩ for input voltage up to 30 V.

Impedance increases with input voltage to approximately 375

kΩ at 750 VAC.

Resistance and Continuity & Diode

Function Range Accuracy

Ω  0 Ω to 9999 Ω ±(2% + 2 dgts)



0.4 V to 0.8 V ±(1% + 3 dgts)

Maximum Open Circuit Voltage: 2.0 V

Overload Protection: 1000 VDC / 750 VAC

Continuity Check

Internal sound activates if the resistance of the circuit under

test is less than 25 Ω. It will then turn off if the resistance is

increased beyond 400 Ω. Speciﬁed from 0 °C to 40 °C.
