4.6 Sourcing frequency
To source a signal use these steps:
1. Switch to the lower display and select
frequency from the primary parameters.
2. Select output, and than choose the frequency
units.
3. Connect the leads to the frequency output
terminals as shown in Figure 12.
4. Enter the desired frequency using the keypad.
5. To change the amplitude, select [FREQ LEVEL]
from frequency level menu.
6. Enter the amplitude.
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. Switch to the lower display 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 13.
2. Select lower display 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.
