7: MEASUREMENT PROCEDURES
WARNING!!!
Do not use the meter when the low battery annunciator
+
_
is displayed.
This may cause the meter to produce inaccurate readings, and lead the
user to believe that no hazard exists, when, in fact, dangerous voltages
or currents are present.
7.1 Using the HOLD feature:
The 9015-A incorporates a convenient HOLD feature. This feature “freezes”
the reading in the LCD when the HOLD button is pressed. To release the
HOLD, press the HOLD button again.
Note:
“H” annunciator appears in the LCD when HOLD is activated.
WARNING!!!
The meter may not show the presence of dangerous potentials when HOLD
is activated. For example, if HOLD is applied when the meter is reading
zero, and 120VAC is subsequently applied, the meter will continue to
read zero. Failure to observe this precaution may result in damage to
the meter or injury to the user.
7.2 Auto Power Off:
The 9015-A has Auto Power Off. This power saving feature automatically
turns the meter off 15 to 20 minutes after turning it on...... thereby
extending battery life.
7.3 DC Voltage Measurement:
WARNING!!!
If the magnitude of the voltage to be measured is unknown, always start
by setting the meter to the highest range, and then to lower ranges,
until a satisfactory reading is obtained.
Do not rotate the RANGE switch with the input applied to the meter.
If the input voltage is higher than 1000VDC (CAT I), 600V DC (CAT II),
or 300V DC (CAT III), do not attempt to measure!
Use Caution when measuring voltages above 50V DC.
