4.9.3 Respectively plug the black test lead and the red test lead into
INPUT— jack and jack.
4.9.4 Connect the test leads to the two terminals of voltage source or
load in parallel for measuring.
4.9.5 Read values in the measurement display area of LCD.
H782 ProcessMultimeter
Operation guidance
Note:
1) Within the low voltage range, if the test lead isn‘t connected to the
circuit under measured, the reading displayed on the instrument
may pulse, which should be considered normal for it is caused by
the high accuracy of the instrument; if connect the test lead to the
circuit under measured, the true measured value will be captured.
4.10 DC current measurement
Warning
Electric shock danger.
It shall power off the circuit under
measured first, then connect the
instrument to circuit in serials for
measuring,
Do not input current higher than
400mA, excessive current will burn out the
protective tube.
4.10.1 Turn the rotary switch to mA or μA
，
if the range is
unknown, it‘d better turn it to mA , LCD shows measuring unit
―mA‖ or ―μA‖ with type ―DC‖ (direct current) at the moment.
4.10.2 If the signal type is ―AC‖, it shall press FUNC to switch it to
―DC‖. If switching is not available, press SHIFT.
