Repeatedly pressing the Select button switches between measuring
direct current (DC) or alternating current (AC). When measuring cur-
rent up to 10 A, first select the measuring range and then connect
the plug of the black (negative) tipped measuring conductor into the
COM socket and the plug of the red (positive) for measuring voltage
into the 10 A socket. If you do not know the current range beforehand,
leave the range setting on AUTO or set the highest range possible
and gradually reduce it as you measure. Connect the measuring
tips to the device or circuit where you will be measuring current.
Turn on the device you want to measure. The screen will display the
current value and polarity (for DC) relative to the red measuring tip.
If „OL“ appears on the screen while in manual mode, set a higher
range.
Current Measurement
(WH3303 or DM633 Measuring Clamp – Optional Accessory)
To measure alternating current over 10 A, it is necessary to use an
AC measuring clamp.
1. Connect the plug of the black (negative) tipped measuring
conductor into the COM socket and the plug of the red (positive)
conductor into the INPUT socket.
2. Switch to the function.
3. Measurement with clamps is done by gripping the measured
conductor with the centre of the clamp.
Only one conductor can be measured at a time.
The measured current value will appear on the screen.
Note: Unifying deviation in measurement sensitivity
1. The sensitivity of measurement using the clamp is 1 A/1 mV. If
you are using a clamp with this sensitivity, then the listed value
is identical to the measured value.
2. When using a clamp with sensitivity other than 1 A/1 mV, the
measured value should be multiplied based on the sensitivity
of the clamp.
Do not touch the measured circuit with your hand or other part
of the body.
