Step 4:
Pressing the
〔
VPEAK
〕
key once switches to the amplitude setting mode. The LCD shows a reading of 1V.
Step 5:
Set the output value digit by digit using each pair of
〔
S
〕
/
〔
T
〕
output setting keys.
Each pair of
〔
S
〕
/
〔
T
〕
keys corresponds to each digit of the LCD reading. Each press of the
〔
S
〕
/
〔
T
〕
key increases
or decreases the digit. Increasing the digit from 9 or decreasing it from 0 causes the digit to overflow or underflow, allowing
the output value to be set without interruption. Holding down the
〔
S
〕
/
〔
T
〕
key changes the digit quickly. The value won’t
change if it is increased or decreased to the Maximum or Minimum value.
Step 6:
Press the
(CYC)
key to enter the pulse number set mode; the LCD will show the default value (1 CYC).
Step 7:
Set the output value digit by digit using each pair of
〔
S
〕
/
〔
T
〕
output setting keys.
Each pair of
〔
S
〕
/
〔
T
〕
keys corresponds to each digit of the LCD reading. Each press of the
〔
S
〕
/
〔
T
〕
key increases
or decreases the digit. Increasing the digit from 9 or decreasing it from 0 causes the digit to overflow or underflow, allowing
the output value to be set without interruption. Holding down the
〔
S
〕
/
〔
T
〕
key changes the digit quickly. The value won’t
change if it is increased or decreased to the Maximum or Minimum value.
Step 8:
To re-enter the frequency set mode, press the
〔
FREQ
〕
key.
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 signals between its output terminals.
Step 10:
Press the
(START)
key to allow the calibrator to source the set number of pulses according to the preset frequency
and amplitude, the LCD will show the “RUN” icon.
Step 11:
When source is complete, the calibrator automatically switches the output OFF and ceases operation. The “RUN”
symbol also switches OFF.
Step 12:
To switch OFF the output manually, press the
(ON)
key again. The ‘’OFF‘’ icon appears on the LCD and no signals
will be sourced between the terminals.
Notes:
z
The frequency range of the pulse can only be changed by pressing
(RANGE)
in the frequency set mode.
z
When the “RUN” symbol switches OFF, the user can change the frequency and amplitude when the source function is
in ‘’ON ‘’ or ‘’OFF‘’.
z
During the pulse sourcing process, pressing the
(START)
key causes the calibrator to switch the output OFF; the “RUN”
icon switches OFF also. Press the
(START)
key again to restart the sourcing function.
z
Restarting the pulse output requires that the source function be in the ‘’ON ‘’state.
