HOW TO MAKE MEASUREMENTS
Before making any measurements read safty precautions. Always
examine the instrument and accessories used with the instrument for
damage, contamination (excessive dirt, grease, etc.) and defects.
Examine the test leads for cracked or frayed insulation and make sure
the lead plugs fit snugly into the instrument terminals. If any abnormal
conditions exist, do not attempt to make any measurements.
VOLTAGE MEASUREMENTS
1. Turn off power to the device under test and discharge all capacitors.
2. Plug the black test lead into the COM input jack on the meter and conne
connect the test lead tip to a grounded point (the reference point for
measurement of voltage).
3. Set the Function/Range switch to the "V / V " position.
WARNING
To avoid possible electric shock, instrument damage and / or equip-
ment damage, do not attempt to take any voltage measurements if the
voltage is above 1000Vdc / 750Vac. 1000Vdc and 750Vac are the
maximum voltages that this instrument is designed to measure. The
"COM" terminal potential should not exceed 500V measured to
ground.
