Voltage
Function
V B
(50 to 500 Hz)
V F
Overvoltage Protection: 1000 V dc/750 V ac
Input Impedance: ≥ 4 kΩ for input voltage up to 30 V. Impedance
increases with input voltage to approximate 277 kΩ at 1000 V/210 kΩ
at 750 V ac.
Resistance and Continuity
Function
Ω R
Overload Protection: 1000 V dc/750 V RMS
Maximum Open Circuit Voltage: 1.5 V
Continuity Check
Internal sounds activate if the resistance of the circuit under test is less
than 25 Ω. It will then turn off if the resistance is increased beyond
150 Ω.
Temperature coefficient multiply by 1.5 when operating temperature is
40 °C - 50 °C.
AC Current
Function
