Model UT20B: OPERATING MANUAL
Measurement Operation (11)
l
The LCD displays " " indicating open-circuit for the tested resistor or the resistor
value is higher than the maximum range of the Meter.
l
When resistance measurement has been completed, disconnect the connection
between the testing leads and the circuit under test.
G. DC Voltage Measurement
Warning
To avoid harms to you or damages to the Meter from electric shock, please
do not attempt to measure voltages higher than 300V / 300V rms although
readings may be obtained.
The DC voltage measurement positions are: 200mV, 2000mV, 20V, 200V and 300V.
To measure DC Voltage, connect the Meter as follows:
1. Set the rotary switch to an appropriate measurement positions in V
21
range.
