Use proper terminals and ranges for the
measurement.

Please use the ranges from high to low if
the current not being confirmed.

When current measurement has been
completed, disconnect the connection
between the test leads and measured
circuit.
C. Resistance Measurement(see figure 5)
Warning
To avoid injury to the user, please do not
attempt the voltage higher than 60V/DC or
30V/AC.
