Safety Summary

WARNING

POSSIBLE ELECTRICAL SHOCK. Calibration and performance tests are to be performed by qualified personnel only. Do not attempt calibration or test procedures unless qualified to do so.

CAUTION

To avoid damage to the multimeter for inputs above 250 Vdc or Vac, disconnect the test leads before changing functions. Do not exceed the maximum input limits.

Maximum Overvoltage Limitations (AC and DC Voltage Functions)

1000V

MAX indicates the maximum voltage between input terminals and earth is ± 1000 V (dc or ac rms).

Do not use the multimeter on any ACV circuit where the maximum impulse overvoltage may be more than 4000Vpk or any DCV circuit where the maximum impulse overvoltage may be more than 2500Vpk between the COM and VOLT terminals. Excessive impulse overvoltage can damage the multimeter voltage functions. Do not measure branch circuits (CAT II) over 600V to earth or service panel circuits (CAT III) over 300V to earth.
