Temperature Measurement
The main display will show the temperature in degrees centigrade, while the middle
sub-display will show the temperature in degrees Fahrenheit
1. Select “TEMP” with the rotary function switch.
2. Insert in the temp probe into TEMP/CAP socket, observe the correct polarity
(narrow and wide tongue). Type K thermocouple probes are to be used
exclusively.
Logic Test This function allows logic level tests in digital circuits.
1. Switch the meter power ON.
2. Set the rotary switch to the “LOGIC” position. The LCD displays “rdy” (ready).
3. Connect the test-leads as follows: COM-input socket (black lead); V-Ohm
socket (red lead).
4. Now connect the other end of the black test-lead to the “ground” point of the
digital circuit and the red test-probe to the supply voltage point (V+ or Vcc)
5. When all leads are connected, press the SET/RESET key to save the “High”
Reference Level.
6. With the black test-lead-at ground, move the red test-probe from the supply
voltage to the desired test points. The multimeter will immediately display one
of the three modes. HIGH MODE: If the level exceeds 70% of the stored
supply voltage “Hi” is displayed. LOW MODE: If the level falls below 30% of
the stored supply voltage, “Lo” is displayed. PASS MODE: If the level is
between the reference values (31% and 69% of the supply voltage), “----“ is
displayed.
