Test For Diodes & Continuity - UNI-T UT90B Operating Manual

Measurement Operation(4)
Note
l For safety sake, the measuring time for high current
should be less than 10 seconds for each measurement
and the interval time between 2 measurements should
be greater than 15 minutes.
l When AC/DC current measurement has been
completed, disconnect the connection between the
testing leads and the circuit under test.
C.Test for Diodes & Continuity
Warning
To avoid possible damage to the Meter and to the
device under test, disconnect circuit power and
discharge all high-voltage capacitors before testing
diodes and continuity.
To avoid harms to you, never attempt to measure
voltages higher than 60V DC/30V AC.
