decreases the digit. Increasing the digit from 9 or decreasing
it from 0 causes the digit to overflow or underflow, allowing

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-

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.
