Note
•
l If the value of current to be measured is unknown, use the maximum measurement
position, and reduce the range step by step until a satisfactory reading is obtained.
•
l For safety sake, the measuring time for high current should be less than 10 seconds
and the interval time between 2 measurements should be greater than 15 minutes.
•
l 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
terminal of the Meter.
Warning!
To avoid damages to the Meter or to the devices under test, disconnect circuit power
and discharge all the high-voltage capacitors before measuring resistance.
The resistance ranges are: 200Ω, 2kΩ, 20kΩ, 2MΩ and 200MΩ.
To measure resistance, connect the Meter as follows:
1. Insert the red test lead into the VΩ input terminal and the black test lead into the COM
terminal.
2. Set the rotary swich to an appropriate measurement position in Ω range.
3. Connect the test leads parallel across with the object being measured.
Note
•
The test leads can add 0.1Ω to 0.3 of error to the slow-resistance (200Ω) measurement.
•
For high resistance (>1MΩ), it is normal taking several seconds to obtain a stable
reading.
•
When there is no input, for example in open circuit condition, the Meter displays "1".
•
When resistance 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
terminal of the Meter.
