OPERATION
Before making any measurements always examine the instrument and acces-
sories used with the instrument for damage, contamination (excessive dirt,
grease, etc.) and defects. Examine the test leads for cracked or frayed insula-
tion and make sure the lead plugs fit snugly into the instrument jacks. If any
abnormal conditions exist do not attempt to make any measurements. Instead
refer to sec. 14 Return for Repairs.
Sec. 9.1
VOLTAGE MEASUREMENTS
1. Insert the black and red test leads into the respective "COM"
and "V-Ω" jacks
2. Place the range selector switch to the 1000DCV position if a DC
voltage is to be measured or into the 500ACV position if an arc
voltage is to be measured.
CAUTION
To avoid possible electric shock, instrument damage and/or equipment
damage, do not attempt to take any voltage measurements if the voltage
is above 1000Vdc/500Vac or if the voltage is unknown. 1000Vdc and
500Vac is the maximum voltages that this instrument is designed to mea-
sure. The "COM" terminal potential should not exceed 500V measured
to ground.
3. Apply the test leads to the two points at which the voltage read-
ing is to be taken. Be careful not to touch any energized con-
ductors with any parts of your body.
4. Turn the range selector switch to the next lower range for a
more accurate reading only if the reading is within that next
lower range.
5. When measurements are completed, disconnect the test leads
from the circuit under test. Remove the test leads from the
instruments.
