Step 7: Set the output value digit by digit using each pair of〔〕/〔〕output setting keys.
Each pair of〔〕/〔〕keys corresponds to each digit of the LCD reading. Each press of the〔〕/〔〕
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〔〕/〔〕
key continuously changes the digit. And the value won't change if it is increased or decreased to the Maxim or
Minimum value.
Step 8: To re-enter into the frequency set mode, press the〔FREQ〕key to set the frequency.
Step 9: Pressing the 〔ON〕 key causes the SOURCE indicator on the LCD to change from ''OFF'' to ''ON '', and
the calibrator sources low level between the output terminals.
Step 10: Pressing the〔START〕key the calibrator sources the set number of pulse responding to the preset
frequency and amplitude, LCD shows the symbol "RUN".
Step 11: When source is complete, the calibrator automatically turns off the output and ceases operation. The
"RUN" symbol disappears from the LCD.
Step 12: To turn off the output, press the 〔ON〕 key once again. The ''OFF'' appears on the LCD and no signals
sourced between the terminals.
Tips:
 The frequency range of the pulse could only be changed by pressing〔RANGE〕key in the frequency set
mode.
When the "RUN" symbol vanishes from the LCD, you can change the frequency ,amplitude and number of

pulse both when the source function is in ''ON '' or ''OFF''.
 In the pulse sourcing process, pressing the〔START〕key causes to stop the output, and the "RUN" mark
