4.7 Sourcing a pulse train
The calibrator can produce a pulse train with an adjustable number of pulses at a desired
frequency. For example, setting the frequency to 60Hz and the number of pulses to 60 would
produce 60 pulses for a period of 1 second. To source a pulse, use the same connection as
for frequency, and proceed as follows:
1. Select the [CONFIG] option from the main menu and select pulse from the primary
parameters.
2. Choose the desired unit and enter the frequency using the keypad.
3. Select the [COUNTS] function from the home menu to enter the number of pulses. Use
[TRIG] to start and stop the signal.
4. The amplitude of the pulse can be adjusted in the same manner as for frequency.

4.8 Sourcing Thermocouples
To source a thermocouple use the following steps:
1. Connect the thermocouple leads to the appropriate polarized TC miniplug, and insert the
plug into the TC terminals on the calibrator, as shown in Figure 15.
2. Select the [CONFIG] option from the main menu, and choose thermocouple [TC] from
the primary parameters.
3. Choose output [OUT] from the input/output control.
4. Select the desired thermocouple type from the sensor types.
5. Enter the temperature using the keypad.
