Basic Operation
6. Set the Ext-Program→On / Off to On to turn on the analog function.
7. Adjust the output of DC Power Supply 1 from -5V to 5V, and adjust the out-
put of DC Power Supply 2, DC Power Supply 3 from -10V to 10V.
The actual output voltage and current of the instrument will change accord-
ing to the following rules:
• Pin 8 controls the actual output voltage of the instrument from 0V to
500V.
• Pin 9, pin 10 monitor the actual output current of the instrument: When
the output current is higher than the upper limit I+ set by pin 9, the instru-
ment outputs the current at the value of I+; When the output current is
lower than the lower limit I- set by pin 10, the instrument outputs the cur-
rent at the value of I-.
6.13 loadAnalogue Function (Ext-Program)
(Optional)
The external analog quantity function means that the user can input an analog
signal in the range of 0V-10 V through the analog quantity input interface for re-
mote setting of the instrument’s input setting value. The external analog quantity
function is not the standard-equipped function for the instrument. It is only avail-
able when the user selects the IT-E167 interface card.
The rear panel of this series of instrument provides an optional interface card in-
tegrating the RS-232 and analog quantity function. The interface card provides
the following capability:
• Remote control of setting values in different modes.
• Remove switching of CC/CV/CR/CW modes.
• Remote monitoring of input voltage/current measurement.
• RS-232 communication interface, please refer to2.6.5 RS–232 Interface
(Optional) for detailed description about the interface.
