Victor VC97 Operation Manual

OPERATION MANUAL
The meter is a high performance, high accuracy, 3 3/4-digit, 32mm digit high by
LCD displaying meter. The function includes DCV, ACV, DCA, ACA,
resistance ,capacitance, frequency, temperature，duty cycle measurement, triode,
diode and continuity test. Also with the function of unit signal displaying ,relative
value measuring ,auto range/ manual range switch ,auto power off and warning
function etc.
SAFETY NOTES
The meter meets with IEC1010standard. Read the notes before operating.
① Before measuring, check the test leads carefully.
② Do not input a value over allowable limited when measuring to avoid electric
shock meter damage.
③ Be careful when measuring voltage over DCV60V, ACV40V.
④ To select correct function.
⑤ The test leads should be taken away from the testing point when changing
function.
⑥ Never take measurement when the test leads are in current terminal.
⑦ Do not try to modify the circuit.
