Thank you for choosing Velleman! Please read the manual thoroughly before bringing this device into service. If
the device was damaged in transit, don't install or use it and contact your dealer.
2. Applications
Voltmeter, thermometer, PH meter, dB meter, Watt meter, current meter, capacitance meter, Lux meter, LCR
meter, other industrial & domestic uses
3. Operation
If needed, add proper voltage dividers (not included) and decimal point wire jumper:
(RA and RB are 1/2 W 0.5% metal film resistors)
Max. voltage to be measured
Proper Voltage Divider
Decimal Point
200 mV
-
Short-circuit P3 - P0
20 V
Disconnect wire jumper in RB.
RB = 9.9M:; RA = 100k:Short-circuit P2 - P0
200 V
Disconnect wire jumper in RB.
RB = 9.99M:; RA = 10k:Short-circuit P3 - P0
500 V
Disconnect wire jumper in RB.
RB = 9.999M:; RA = 1k:-
xConnect an appropriate power supply to the panel meter (depending on the model, see Technical
Specifications).
xFor ranges other than 200mV, generate an input voltage of exactly half the measuring range (e.g. 100V for
200V range) and carefully adjust the semi-fixed resistor R2 until you obtain the same reading on the
display.
xConnect the input voltage to be measured to +Vin and -Vin. The input voltage should be DC only.
