Safety & Warnings
This operation manual contains information and warnings that must be followed to ensure user operation safety and to retain the meter safety condition. To ensure personal safety and to avoid damaging the meter and the equipment connected, read “Getting Started” in Section 2-2 before using the meter.
The meter has been designed and tested according to EN61010-1 (IEC1010-1), Safety Requirements for Electronic Measuring Apparatus. This manual contains information and warnings which must be followed to ensure safe operation and retain the meter in safe condition. Use of this instrument in a manner not specified herein may impair the protection provided by the equipment.
WARNING: To avoid electrical shock or other injury:
– Be sure the meter is in good operating condition and avoid working alone.
– Follow all safety procedures for equipment being tested.
– Inspect the test leads for damaged insulation or exposed metal. Check test lead continuity. Damaged leads should be replaced.
– This equipment operates from a power source that does not apply more than 250V rms between the supply conductors or each supply conductor and ground. A protective ground connection by way of the grounding conductor in the power cord is essential for safe operation.
– This equipment is grounded through the grounding conductor of the power cord. To avoid electrical shock, plug the power cord into a properly wired receptacle before connecting to the equipment input or output terminals.
– To avoid explosion, do not operate this product in an explosive atmosphere.
– To avoid personal injury, do not remove the cover or panel. Refer servicing to qualified personnel.
– Select the proper function for your measurement.
– To avoid electrical shock, use caution when working above 60V dc or 30V ac RMS.
– Disconnect the live test lead before disconnecting the common test lead.
– Disconnect the power and discharge high-voltage capacitors before testing in Q and diode.
– When making a current measurement, turn the circuit power off before connecting the meter in the circuit.
– To avoid fire hazard, always use a specified fuse.
– Use clamp-on probes when measuring circuits exceeding 10 amps.
– When servicing the meter, use only the replacement parts specified.
– Do not allow the meter to be used if it is damaged or if its safety is impaired.
The meter is safety-certified in compliance with EN61010-1 and EN61010-2-31 (IEC1010-1 & IEC1010-2-31) Installation Category II 600V and CAT I 1000V Pollution Degree 2. In order to maintain its insulation properties, please be sure to use with the standard or compatible test probes.
CE requirement: Under the influence of R.F field according to standard, the supplied test leads will pick up induced noise. To have better shielding effect, a short-twisted lead should be used.
