• Connect the red lead to the anode and the black lead to the
cathode of the diode under testing.
Note:
• The meter will show approximate forward voltage drop of the
diode.
• If the lead connections is reversed, only '1' will be displayed.
Continuity Testing
• Connect the black test lead to COM jack and the red to VΩmA
jack.
• Set the rotary switch at the range position.
• Connect test leads across two points of the circuit under
testing.
• If continuity exists (i.e. resistance less than about 50Ω), the
built-in buzzer will sound.
Note:
If the input is an open circuit, the figure '1' will be displayed.
Measuring Capacitor
• Connect the black test lead to Cx-jack and the red to Cx+ jack.
• Set the rotary switch at the desired 20uF/200nF range position.
• Before inserting capacitor under measurement into capacitance
testing socket be sure that the capacitor has
been discharged fully.
Measuring Battery
• Load resistance
1.5v range: 36Ω
9V range: 360Ω
12V range: 450Ω
• The 1.5V battery is good when the display is more than 33mA.
• The 9V battery is good when the display is more than 18mA.
• The 12V battery is good when the display is more than 14mA.
MAINTENANCE
• Before attempting to remove the battery door or open the case,
be sure that test leads have been disconnected from
measurement circuit to avoid electric shock hazard.
• To avoid electrical shock, remove test leads from measurement
circuits before replacing the fuse. Replace fuses only with a
specified rating: F-200mA/250V fuse.
• Replace the test leads if the lead is damaged or exposed in
any way. Only replace leads with the same type and
specification.
• Use only moist fabric or a small amount of detergent, never
use chemical solutions for cleaning.
• Do not use the meter before the back cover is properly closed
and screw secured.
• Upon any signs of abnormality, stop operation immediately and
send the meter for maintenance by a qualified technician.
