Connect the diode to the terminals. For forward bias, connect the
probe from input terminal “
HI
” to the positive end of the diode, and
connect the probe from input terminal “LO” to the negative end of
the diode.
3
Set voltage bound via pressing SHIFT + CONT buttons.
When ready, press ENTER. (Or skip this step if you wish to use the
default voltage bound.)
4
Press SHIFT + CONT buttons to select the diode testing function
and observe the reading on the display.

3.7 Temperature Measurements
The ATM3500A supports thermocouples and resistance temperature
detector (RTD) types of probes. For thermocouples, ATM3500A
supports 7 types: E, J, K, N, R, S and T. Please refer to
Table 3-1
for
their temperature ranges. Be sure that the temperature function is
configured for the right sensor type before making measurements
(Refer to 4.1.8 for how to make the sensor configuration).
In general, RTDs have a better accuracy and long-term stability than
thermocouples. The default RTD type in ATM3500A is PT100
(Temperature Range:
-200~850)
and the thermocouple is type K.
