Operations
Operating Instructions
If the measured current exceeds the set value over a long period of
time then the meter can heat up. This can impair the functional reli-
ability of the internal circuitry.
To avoid discharges or inaccurate readings, do not measure currents
on high-voltage lines (over 300 V).
The meter has been set at the factory for DC mode.
Measuring AC currents
|
Set the function switch as needed.
|
Use the Select button to choose the AC current range
"AC TRMS".
|
Encircle one of the wires being measured with the current trans-
former (the clamping jaws) Make sure that the clamp is completely
closed.
|
Read the measured value displayed in the "TRMS" field.
Measuring DC currents
|
Set the function switch as needed.
|
Encircle the wire being measured with the current transformer (the
clamping jaws). Make sure that the clamp is completely closed.
Make sure the polarity indicator is correct!
|
Read the measured value.
|
It may be necessary to zero-calibrate before measuring. To calibrate,
open the close the clamps repeatedly (with no wire inside). Then
wait until the displayed value has steadied and press the ZERO but-
ton. The value in the display should change to about 0.00 and ZERO
appears in the display.
