3.2.8 Current measurement
To avoid damage to the Meter or injury if the fuse
blows, never attempt an in-circuit current
measurement where the open-circuit potential to
earth is greater than 1000V.
To avoid damage to the meter, check the meter's
fuse before proceeding. Use the proper terminals,
function, and range for your measurement. Never
place the probes in parallel with a circuit or
component when the leads are plugged into the
current terminals.
The Meter's current ranges are 600.0A, 6000A,
60.00mA, 600.0mA, 6.000A and 10.00A.
To measure current (set up the Meter as shown in Figure
3-6):
1. Turn off power to the circuit. Discharge all high voltage
capacitors.
2. Set the rotary switch to the A, mA or A range.
3. Press the SELECT key to select DCA or ACA
measuring mode.
4. Connect the black test lead to the COM terminal and
the red test leads to the mA terminal for a maximum of
600mA. For a maximum of 10A, move the red test lead to
the A terminal.
5. Break the circuit path to be tested.
Touch the black probe to the more negative side of the
break; touch the red probe to the more positive side of the
break. (Reversing the leads will give a negative reading,
