Model UT107: OPERATING MANUAL
If the value of voltage to be measured is unknown,
use the maximum measurement position (1000V) and
reduce the range step by step until a satisfactory
reading is obtained.
The LCD displays “1” indicating the existing selected
range is overloaded, it is required to select a higher
range in order to obtain a correct reading.
In each range, the Meter has an input impedance of
approx. 10M . This loading effect can cause
measurement errors in high impedance circuits. If the
circuit impedance is less than or equal to 10k , the
error is negligible (0.1% or less).
When DC voltage measurement has been completed,
disconnect the connection between the testing leads
and the circuit under test.
