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
PULSE
.
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.
