Prokit's Industries MT-1233С - Manual (Page 12)

3. Connect the red test lead to the anode! of the
diode to be measured and black test lead to
cathode.
4. The forward voltage drop in mV will be displayed.
If the diode is reversed, figure "1" will be shown.
TEMPERATURE MEASUREMENT
(MT-1233C only)
1. Connect the K type thermoelectric couple to
"VΩmA" and "COM" jacks.
2. RANGE switch to TEMP position.
3. The display will read Temperature value ℃
AUDIBLE CONTINUITY TEST
1. Red lead to "VΩmA", Black lead to "COM".
2. RANGE switch to “
”position.
3. Connect test leads to two points of circuit to be
tested. If the resistance is lower than 30Ω±20Ω,
the buzzer will sound.
TEST SIGNAL USE (MT-1233D only)
1. RANGE switch to "
”position.
2. A test signal (50Hz) appears between "VΩmA"
and "COM” jack, the output voltage is approx 3V
p-p with about 50KΩ impedance.
