DC VOLTAGE MEASUREMENTS

fumes or moisture. Also, the fingers should never touch the metal parts of the test probes since body resistance can cause erroneous readings - particularly on the high ohmmeter ranges. Care: Although this instrument is portable and rugged it should be treated with care. Do not drop it or handle It roughly. Avoid placing it on a bench where machine tools are used or severe vibration is encountered. When possible keep it in a place of moderate temperature. Avoid subjecting it to extreme temperatures and severe temperature changes. If the tester has not been used for a long period of time, rotate the switch in both directions several times to wipe the switch contacts for good contact. DC VOLTAGE MEASUREMENTS 0-3 thru 0-300 Volts: 1. Insert test leads in VOM and COM lacks 2 Set switch to appropriate DCV range 3 Connect probes across voltage to be measured 4 Read voltage on the black AC-DC scale 0-1200 Volts 1 Insert test leads in COM and 1200 VDC jacks 2 Set switch to 3 DCV position 3 Connect probes across voltage to be measured 4 Read voltage on the black AC-DC scale DO NOT TOUCH THE VOM while it is connected to high voltage! BE CAREFUL around high voltage! 7
