- Caution:
Do not insert the testing leads during current measurement to avoid electric shock.
The current measurement must be taken with safeguard protection. Press the REL button
to return to zero before the DC current measurement, and meanwhile the center hole of jaw
should be perpendicular to the current direction to ensure accuracy.
The open circuit zeroing reading may be relatively large after (high) DC current
measurement. Please perform theAC current detection again to counteract the remanence
signal by alternating electric field.
AC/DC Voltage and Voltage Frequency (% duty cycle) Measurement
- Select the corresponding function scale.
- Insert the red test lead into the "positive" jack, and the black into the "COM" jack.
- Connect test leads with both ends of the measured objects.
Caution:
- Do not input voltage above 600V to prevent electric shock or damage. The input
impedance of each range scale is 10MΩ, this load effect in high resistance measurement may
cause error. If the input impedance is lower than 10kΩ, the error can be ignored (≤0.1%).
- Be cautious to avoid electric shock when measuring high voltage.
- Please check the functions by applying a known voltage before use.
