Step 7: Set the number of pulses value digit by digit using each pair of
and
output setting keys. 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 under-
flow, 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 (
), thus reverting to the mode of
sourcing continuous pulse trains.
Step 8: Pressing the
key causes the
indicator on the LCD
to change from
to
. The calibrator sources the preset
number of pulses with the preset frequency and amplitude
between the output terminals.
Step 9: When source is complete, the calibrator automatically turns
off the output and ceases operation. The
appears on the
LCD and the output terminals are open-circuited.
TIP
To stop sourcing pulses halfway, press the
key when pulse output is in progress.
