OPERATION
Please make sure that you have already read and fully understand the WARNING section on page 1.
Making Measurements with the AC Current Probe Model MN03
• Connect the black lead of the current probe to "c
your DMM or other
range). Clamp the probe around the conductor to be test ed. Select the low er range until y ou obtain the
best resolution. Read the value display on the DMM and multiply it by the probe ratio (1000/1). (If reading
= 59mV, the current flowing through the probe is 59 x 1000 = 59A)
• For best accuracy, avoid if possible, the proximity of other conductors which may create noise.
Tips for Making Precise Measurements
• W hen using a current probe w ith a meter, it is im portant to select the r ange that prov ides the best
resolution. Failure to do this may result in measurement errors.
• Make sure that probe jaw mating surfaces are fr ee 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 factory replacement parts.
• To avoid electrical shock, do not attempt to perform any servicing unless you are qualified to do so.
• To av oid electrical shock and/or damage to the in strument, do not get w ater or other foreign agents
into the probe
Cleaning
To ensure optimum performanc e, 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 jaw s, use v ery fine sand paper (fine
600) to avoid scratching the jaw, then gently clean with a soft oiled cloth.
REPAIR AND CALIBRATION
You must contact our Serv ice Cent er for a Customer Serv ice Author ization number (CSA#). This
ensure that when your instrument arrives, it will be tracked and processed promptly. Please write the CSA#
on the outside of the shipping container.
(Or contact your authorized distributor)
NOTE: All customers must obtain a CSA# before returning any instrument.
