OPERATION

Please make sure that you have already read and fully understand the WARNING.
Making Measurements with the AC Current Probe Model MN05

Connect the black lead of the current probe to common and the red lead to the AC voltage range on your DMM or other voltage measuring instrument. The 10 A range has an output signal of 1 mV/mA AC. This means that for 10 A AC in a conductor around which the probe is clamped, 10 VAC will come out of the probe leads to your DMM or instrument. The 100 A range has an output signal of 1 mV/A AC. This means that for 100 AAC in a conductor around which the probe is clamped, 100 mVAC will come out of the probe leads to your DMM or instrument. Select the range on your DMM or instrument which corresponds best to the measured current. If the current magnitude is unknown, start with the highest range first and work down until the appropriate range and resolution is reached. Clamp the probe around the conductor. Take the reading on the meter and multiply it by the output signal used to obtain the measured current. (e.g. If the meter reads 100.5 mV (range 1 mV/mA), then current equals 100.5 mAAC). Unclamp the probe from the conductor before disconnecting it from your DMM or instrument.
For best accuracy, avoid if possible, the proximity of other conductors which may create noise.

Tips for Making Precise Measurements

When using a current probe with a meter, it is important to select the range that provides the best resolution. Failure to do this may result in measurement errors.
Make sure that probe jaw mating surfaces are free of dust and contamination. Contaminants cause air gaps between the jaws, increasing the phase shift between primary and secondary. It is very critical for power measurement.

MAINTENANCE

Warning

For maintenance, use only original replacement parts.

To avoid electrical shock, do not attempt to perform any service on the device unless you are qualified to do so.
To avoid electrical shock and/or damage to the instrument, do not allow water or other foreign agents to come into contact with the probe.

Cleaning
To ensure optimum performance, it is important to keep the probe jaw mating surfaces clean at all times. Failure to do so may result in error in readings. To clean the probe jaws, use very fine sand paper (fine 600) to avoid scratching the jaw, and then gently clean with a soft, oiled cloth.

REPAIR AND CALIBRATION

You must contact our Service Center for a Customer Service Authorization number (CSA#).
