Measurement Operation(3)

Note

l In each range, the Meter has an input impedance of

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).

l When AC voltage measurement has been completed,

disconnect the connection between the testing leads

and the circuit under test and remove testing leads

from the input terminals.

Warning

To avoid harms to you, do not attempt to input voltages

higher than 60V DC or 30V rms AC.

To avoid damages to the Meter or to the devices

under test, disconnect circuit power and discharge

all the high-voltage capacitors before measuring

resistance.
