11. BAT. LOAD TEST Function: To test small batteries. Four
(4) ranges: 1.5, 6, 9 and 12 volts.
12. Function/Range Selector Switch: Selects desired func-
tion or range.
13. ACV Function: Measures AC voltages. Two ranges: 200
and 500 volts.
14. OFF Function: Turns unit "off" when function is selected.
15. Liquid Crystal Display (LCD): Displays results of tests or
measurements.
Preparation and Caution Before Use
•
Inspect the digital multimeter for damage to the case. Do not
use if cracked, distorted, excessively dirty or any abnormal
condition exists.
•
Inspect the test leads for damage. Check for cracked insula-
tion, broken or damaged probes, loose or bent probe pins. Do
not use if any abnormal condition exists.
•
Set the Function/Range Selector Switch to the proper range
BEFORE taking measurements. If the range/function must
be switched during a test, ALWAYS remove the test leads
from the circuit being measured before switching settings.
•
To avoid possible electric shock, instrument damage, and/or
equipment damage when taking voltage or current measure-
ments, DO NOT exceed the maximum value of the selected
range.
•
If the unit is used near high noise Radio Frequency (RF) gen-
erating equipment (spark plug wires, ignition coils or alterna-
tor), the display may become unstable or indicate large errors.
If you obtain erratic readings during use, isolate the Multimeter
as far away as possible from these components.

TESTING PROCEDURES

A. AC/DC VOLTAGE MEASUREMENT
To avoid possible electric shock, instrument damage
and/or equipment damage, DO NOT attempt to measure
voltages ABOVE 500V AC/DC or take measurements if
the voltage is unknown. 500V AC/DC between the COM
and V jacks is the maximum voltage that this instrument
is designed to measure. The "COM" terminal potential
should not exceed 300V AC/DC measured to ground.
