Step 5: 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 de-
fault value (0.1 V).
Step 6: Press the
key once again to show
on the LCD.
Then, press the
key one more time to revert to fre-
quency setting mode.
Step 7: Pressing the
key causes the
indicator on the LCD
to change from
to
. The calibrator sources a continu-
ous pulse train with the preset frequency and amplitude be-
tween the output terminals.
Step 8: To turn off the output, press the
key once again. The
symbol appears on the LCD and the output terminals are
open-circuited.
TIP
To change the frequency range, place the calibrator in frequency setting mode with
the
key. Then, change the frequency range using the
key.
