Diode Measurement
1. Set the selector switch to the appropriate Ω range to be used.
NOTE: To test the diode while current below 0.060 mA at X 10K
range; current below 0.15 mA at X 1K range; current below 1.5
mA at X 100 range; current below 15 mA at X 10 range; current
below 150 mA at X 1 range.
2. For IF (forward current) test, put the BLACK test lead to the
“-COM” jack and the RED test lead to the Red “+” jack. And
then connect the Black probe to the Positive terminal of the
Diode, the Red probe to the Negative terminal of the Diode.
For IR (reverse current) test, reverse the connection.
3. Read the value IF or IR of the diode on the LI scale.
4. Read the linear (forward voltage) VF of the diode on the LV
scale.
Continuity Test
WARNING: DO NOT APPLY VOLTAGE TO MEASURING
TERMINAL WHILE RANGE SWITCH IS IN OHM POSITION.
Set the selector switch to the BUZZ range. Connect the test leads
to two points of circuit. If the resistance is lower than 200 Ohm
approx., the Beeper sounds.
Note: Battery voltage is sufficient for Buzzer operation as long as
the Zero Ohm pointer can be adjusted to the Zero scale place.
Note: If connected incorrectly with the voltage, quickly
remove the test leads from the circuit as to avoid damage to
this tester..
(This tester can afford the voltage <250V DC/AC rms. for the
period of 5 seconds max.)
