1. Select a channel to set up:
G D Look for the desired channel number in the right display.
2. Press the following buttons to change the setup:
F SET and FUNC come on bright, along with the present setting for measurement
function.
G D Cycle through the choices for measurement function.
E Accept your choice of measurement function.
For resistance measurements, continue on with steps 3 and 4. For temperature
measurements, skip to step 5.
3. For dc volts, ac volts, resistance, or frequency, the instrument now provides a choice
of measurement ranges. Press the buttons as follows:
G D Cycle through the choices.
E Accept your choice.
For dc volts, ac volts, or frequency, the configuration is now complete for this
channel. The instrument returns to Inactive Mode.
4. For resistance measurements, one more step is required to specify 2-terminal (2T) or
4-terminal (4T) measurements. Since 4-terminal measurements require two
channels, 4-terminal measurements can be set up on channels 1-10 only. For each 4-
terminal channel, a corresponding channel (11-20) ten numbers higher is reserved
for the additional two connections required. Press the buttons as follows:
G D Choose between two terminals (2T) and four terminals (4T).
E Accept your choice. The instrument returns to Inactive Mode.
5. If you’ve specified temperature measurements, the instrument provides a choice of
thermocouple types or Platinum RTD. Press the buttons as follows:
G D Cycle through the thermocouple choices. "Pt" is the RTD choice.
E Accept your choice.
If you selected one of the thermocouple types, channel configuration is complete; the
instrument returns to Inactive Mode.
6. If you selected "Pt" (for RTD-based measurements), use the following buttons to
specify 2-terminal (2T) or 4-terminal (4T) measurements and the R0 value.
Since 4T measurements require two channels, 4-terminal measurements can be set
up on channels 1-10 only. For each 4T channel, a corresponding channel (11-20) ten
numbers higher is reserved for the additional two connections required.
G D Choose between two terminals (2T) and four terminals (4T).
E Accept your choice.
Now choose the R0 (ice point) value (preset to 100.00). Use J or H to move
between digits. Use G or D to select a value for each digit.
E Accept your choice. Channel configuration is complete; the instrument returns
to Configuration Mode.
