Diode Testing
Do not conduct diode or continuity measurements on live circuits.
Make sure all capacitors in the circuit are depleted.
1.
Connect the red test lead to "V
Ω
mA" jack and the black one to the
"COM" jack (the red lead has a positive polarity "+".).
2.
Set the rotary switch in the " " position.
3.
Connect the red test lead to the anode of the diode to be tested and
the black test lead to the cathode of the diode. The approx. forward
voltage drop of the diode will be displayed. If the connection is
reversed, the display will merely show a "1".
14.
Continuity Testing
Do not conduct diode or continuity measurements on live circuits.
Make sure all capacitors in the circuit are depleted.
1.
Connect the red test lead to "V
Ω
mA" and the black one to "COM".
2.
Set the range switch in the " " position.
3.
Connect the test leads to two points of the circuit to be tested. If
continuity exists, the built-in buzzer will sound.
15.
Battery Testing
1.
Connect the red test lead to the "V
Ω
mA" jack and the black test lead to
the "COM" jack (the red lead has a positive polarity "+").
2.
Set the rotary switch in the appropriate BATT range position.
3.
Connect the test leads to the battery’s terminals and read the LCD
display.

Battery and Fuse Replacement
WARNING:
To avoid electrical shock
always
disconnect the test
leads prior to opening the housing. To prevent fire hazards, only use
fuses with the same ratings as specified in this manual.
Remark:
refer to the warning on the battery compartment
There are no user-serviceable parts inside the device.
Refer to an authorized dealer for service and/or spare parts.
Disconnect the test leads from the test points and remove the test
leads from the measuring terminals before replacing the batteries or
fuses.
