100 F 0.1 F
Overload Protection: 600V DC/AC rms
NOTE: Accuracy does not include error caused by the
capacitance of test lead and the meter. To reduce the
error, use Relative mode. For range 100 F, wait about 30
seconds for reading to settle.
DIODE TEST
Range Introduction
The approximate forward
voltage drop of the diode
will be displayed.
2V If the voltage drop is more
than 2.0V, the display
shows the over-
range indicator "OL".
Overload Protection: 600V DC/AC rms
CONTINUITY TEST
Range Introduction
The built-in buzzer will
sound if the resistance
is less than about 20 .
The buzzer will not sound
if the resistance is more
than 150 .
Overload Protection: 600V DC/AC rms
WARNING
Do not take readings unless the battery door is
securely closed.
USING RELATIVE MODE
Selecting Relative Mode stores the present reading as
a reference for subsequent measurements and sets the
dis play to zero (0).
To enter Relative Mode, press the REL
Q
symbol " " will appear on the LCD display.
Q When you perform a new measurement, the display
shows the difference between the first (reference)
and the new measurement.
Press REL again to exit Relative mode and clear

the symbol.
NOTE: For capacitance measurements, the meter
remains in Autorange mode when you select Relative
mode. The actual capacitance to be measured must
not exceed 100 F even if you use Relative mode.
For other measurements which have both Autorange
mode and Manual Range mode, the meter changes to
Manual Range mode when you select Relative mode.
The actual value of the object under test must not exceed
the full-range reading of the selected range when you
use Relative mode. Use a higher measurement range if
necessary.
MANUAL RANGING AND AUTORANGING
See Figure 4.
The meter defaults to Autorange mode in measurement
functions which have both Autorange mode and Manual
range mode. When the meter is in Autorange mode,
AUTO is displayed.
Press the RANGE button to enter the manual range

mode. The AUTO symbol will disappear.
Each press of the RANGE button increases the
Q
range. When the highest range is reached, the meter
wraps to the lowest range.
To exit the manual range mode, press and hold down
Q
the RANGE button for about 2 seconds. The meter
will return to Autorange mode and the symbol AUTO
will appear.
NOTE: The RANGE button is disabled in diode,
continuity and capacitance measurement functions.
DATA HOLD MODE
Press the HOLD button to hold the present reading

on the display. The symbol HOLD will appear on the
display as an indicator.
Press the button again to exit Data Hold mode. The
Q
symbol HOLD will disappear.
BUILT-IN BUZZER
Q When you press a button, the built-in buzzer will
sound a beep if the press is effective.
The buzzer will beep several times about 1 minute

before the meter turns off automatically, and give 1
long beep before the meter turns off automatically.
ALLIGATOR CLIPS
A set of alligator clips is included with the multimeter, one
for the black lead, and another for the red lead. When
you want the meter to remain connected to a circuit, but
want to keep your hands free for other operations, the
alligator clips will hold the leads in place.
