Step 6:
To re-enter into the frequency set mode, press the
〔
FREQ
〕
key to set the frequency.
Step 7:
Pressing the
〔
ON
〕
key causes the SOURCE indicator on the LCD to change from ‘’OFF‘’ to ‘’ON ‘’. The calibrator
sources constant pulse signals responding to the preset frequency and amplitude between the output terminals.
Step 8:
To turn off the output, press the
〔
ON
〕
key again. The ‘’OFF‘’ icon appears on the LCD and no signals are sourced
between the terminals.
Notes:
z
The frequency range can only be changed by pressing the
〔
RANGE
〕
key in the frequency set mode.
z
The frequency value and range can be changed when the frequency source function is in the ‘’ON ‘’ or the ‘’OFF‘’ state.
5.5 Sourcing a Number of Pulses
The calibrator can source a preset number of pulse signals according to the preset frequency and amplitude.
Step 1:
Using the
〔
PULSE
〕
key, select the pulse source function. The LCD shows the default value 10 Hz.
Step 2:
Using the
(RANGE)
key, select a frequency range (100Hz / 1KHz / 10Hz). The selected function, the default range
source value, and the unit of measure are shown in the lower portion of the LCD.
Step 3:
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 continuously changes the digit quickly.
The value won’t change if it is increased or decreased to the Maximum or Minimum value.
Step 4:
Pressing the
〔
VPEAK
〕
key 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 continuously 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 number of 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 continuously 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.
