UT108/109 OPERATING MANUAL
Note
● 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.
● Please take extra care when measuring high voltages to avoid electric shock.
● In each range, the Meter has an input impedance of approx. 10MΩ. this loading effect
can cause measurement errors in high impedance circuits. If the circuit impedance is
less than or equal to 10kΩ, the error is negligible (0.1% or less).
● When voltage measurement has been completed, disconnect the connection between
the testing leads and the circuit under test, and remove the testing leading away from
the input terminals of the meter
