Measuring Temperature
NOTE: To avoid possible damage to the meter or other equipment,
remember that while the meter is rated for -4˚ to 1382˚F (-20˚ to
±750˚C), the K-type thermocouple provided with the meter is rated to
900˚F. For temperatures out of that range, use a higher rated
thermocouple.
1. Set the rotary switch to the 1400˚F or 750˚C position. The display
will show the temperature of the environment.
2. Connect the negative “ - ” plug of the K-type thermocouple to the
“ COM ” jack, and the positive “ + ” plug to the “ V
Ω
RPM ” jack.
3. Connect the K-type thermocouple to the object to be measured.
4. Read the reading on the display. This it is the true temperature of
the measured object.
Measuring DWELL Angle
1. Connect the black test lead to the “ COM ” jack and the red test
lead to the “ V
Ω
RPM ” jack.
2. Set the rotary switch to the “ DWELL ” range according to the
cylinders of the engine to be measured.
3. Connect the test lead to the iron bars or the negative pole of the
battery, and the red test lead to the distributor terminal of the
ignition coil.
4. Start the engine to set it in idle-speed. Read the value of the
DWELL angle on the LCD.
Testing Duty Cycle
1. Connect the black test lead to the “ COM ” jack and the red test
lead to the “ V
Ω
RPM ” jack.
2. Set the rotary switch to the “ DUTY ” position.
3. Connect the test leads to the circuit to be measured.
4. Read the reading on the display.
