Diode and Continuity Measurements
1. Connect red test lead to the "+" terminal and black test lead to the "COM" terminal.
2. Set the range switch to the diode test position "
".
3. Connect the red test lead to the anode side and black test lead to the cathode side of the
diode being tested.
4. Read the forward voltage value on LCD. The value for a good diode is 0.3VDC for
germanium diodes and 0.7VDC for silicon diodes.
5. If the test lead connection is reversed, the digital reading should reflect an open circuit
condition if the diode is good.
6. Continuity measurement: When the reading is below 50mV an audible tone will sound.
MIN/MAX Recording
1. Set the Function Switch to the Voltage or Current position.
2. To record and view MIN and MAX values while taking measurements, press the MIN MAX
button.
3. Now while measurements are being taken, the display only the MIN or the MAX reading. Use
the MIN MAX button to toggle between MIN and MAX readings. The LCD will display MIN or
MAX as selected.
4. To exit this mode, press and hold the MIN MAX button until the MIN and MAX display icons
disappear from the LCD.
Peak Detection
Peak Detect mode is used to capture fast transients signals (to 0.1ms) such as those caused by
motor startup surges or arc welding equipment switching.
1. Set the Function Switch to the Current or Voltage position.
2. Engage the Peak detector by pressing and holding the READ button until a short
beep is heard.
(Note that if the button is held longer, a longer beep will sound and the meter will be in the
datalogging view mode; refer to the datalogging section for more info).
3. The LCD will display 'P-P+' when the Peak Detect mode is accessed correctly. Use the PEAK
button to toggle between ' P+ Max' (captures positive polarity peaks) and 'P- MIN' (captures
negative polarity peaks).
4. To exit the Peak mode, press and hold the PEAK button for two seconds (until the P- and P+
icons disappear).
5. Take a Voltage or Current measurement on a transient signal and the display will show the peak
of the pulse. The fastest surge the meter can detect is 0.1ms.
Data Hold
1. To freeze a displayed reading, press the HOLD key.
2. The HOLD icon will appear on the top of the LCD to let the user know that the meter is in the
Data Hold mode.
3. To return the meter to the normal operation mode, press the HOLD key again. The HOLD icon
will extinguish.
