- Verify the instrument is operating correctly by measuring a known voltage before use. If in doubt, have the instrument serviced. - Do not apply more than the rated voltage as marked on the instrument between terminals, or between any terminal and earth ground.
Maintenance Do not attempt to repair this Instrument. It contains no user-serviceable parts. Repair or servicing should only be performed by qualified personnel. This instrument should be calibrated yearly, or more frequently if used in harsh conditions or if it is suspected of being inaccurate. For calibration and repair contact RS Components - the address is given at the end of these instructions.
Power On / Off • When first turned on, the instrument displays the remaining capacity of the battery. Replace the battery when 0% is shown or the low battery symbol “<” remains visible in the display. After a successful battery self-test, the instrument will automatically select resis- tance (Ω)/continuity mode.
Self-Testing Aid Fail of usage Ready to use • Do not attempt to measure while power- ing up, as it will cause the self-test to fail. Caution If “FAIL” is shown in the display, do not use the instrument as an internal fault has occurred.
