4.5.3 Using the Contact Output
You can turn on or off the output terminals. This setting is possible
for both the mode of sourcing a continuous pulse train and the mode
of sourcing a given number of pulses. An FET is used as the contact
switching device. Since the way of using the contact output is the
same for both the source of continuous pulse trains and the source
of a number of pulses, this subsection only refers to the procedure
for continuous pulse trains.
Step 1:
Using the function selector switch, select
.
The LCD shows the default frequency
.
Step 2:
Using the
key, set the frequency range. Each press of
the
key cycles through the 500.0 Hz, 1000 Hz and
10 kHz options.
Step 3:
Set the output value digit by digit using each pair of
and
output setting keys.
Each pair of
and
keys corresponds to each digit of the
LCD reading. Each press of the
or
key increases or
decreases the digit. Increasing the digit from 9 or decreasing
it from 0 causes the digit to overflow or underflow, allowing
you to set the output value without interruption. Holding down
the
or
key continuously changes the digit in question.
Pressing the
key initializes the output setpoint to the
default value (differs depending on the frequency range).
Step 4:
Pressing the
key once switches to amplitude setting
mode. The LCD provides a reading of
.
Step 5:
Changing the reading of
to
with the
key causes
the calibrator to enter contact output mode.
Step 6:
Press the
key once again to show
on the LCD.
Then, press the
key one more time to revert to
frequency setting mode.
