Trigger setting
You can specify a variety of trigger settings on the Model 2100, including the number of samples
per trigger, the number of triggers per event, reading hold, and the trigger delay for your
measurements.
Number of samples on each trigger
By default, the multimeter takes only one reading on each trigger, but you can instruct the
multimeter to take a specific number of readings (up to 50,000) each time it receives a trigger. The
sample count is stored in volatile memory. It is lost once power is disabled/lost.
To set the number of samples using the front panel:
1. Press the MENU key and use the PREV and NEXT keys to select TRIG, then press ENTER.
2. Next, use the PREV and NEXT keys to select N SAMPLE, then press ENTER.
3. Set the desired number of readings by pressing the up and down arrow keys to increase or
decrease the number, and use the PREV and NEXT keys to move through the digits. Refer
to Figure 4-13 for the location of the keys.
Procedures: MENU TRIG N SAMPLE <Number>
Figure 4-13
Trig submenu
To set the number of samples using a remote interface:
1. Use the following command to set the number of samples from your PC terminal:
SAMPle:COUNt <value>
Number of triggers
Although the meter normally takes one trigger before returning to the idle state, you can manually
specify the number of triggers it accepts before it returns to the idle state (this can only be done
using the remote interface).
To set the number of triggers between each idle state:
1. Use the following command from your PC terminal to set multiple triggers between each idle
state:
TRIGger:COUNt <value>
