MEASURING AC OR DC CURRENT (see figure 12)
Warning
To avoid personal injury or damage to the Meter:
• Never attempt to make an in-circuit current measurement when the open-circuit potential
to earth is greater than 600V.
• Inspect Meter's fuses before testing. Broken fuses may damage to the Meter or hurt
yourselves
• Use the proper terminals, switch position, and range for your measurement.
• Never place the probes in parallel with circuit or component when the leads are plugged
into the current terminals.
The current ranges are 60.00mA and 600.0mA.
To measure current, connect the Meter as follows:
1. Insert the red test lead into the mA terminal and the black test lead into the COM terminal.
2. Set the rotary switch to mA
measurement mode.
3. Connect the test leads across with the object being measured. The measured value shows on
the display.
4. AC Current displays True RMS value.
Note:
• If the value of current to be measured is unknown, set THE Meter to autoranging or use the
maximum measurement position 600.0mA and reduce the range step by step until a satisfactory
reading is obtained.
• For safety sake, when measuring high current, each measurement time must be less than 10
seconds with an interval more than 15 minutes.
• When Current measurement has been completed, disconnect the connection between the testing
leads and the circuit under test, and remove the testing leads away from the input terminals of
the Meter.
