57 ASCII)
y
= A ............ set the value in the setpoint 1
y
= B ............ set the value in the setpoint 2

Possible instrument responses:
-
correct reception:
&&aa!\ckckCR
-
incorrect reception:
&&aa?\ckckCR
Example: to set 500 in the setpoint no. 3, the PC must transmit
the following command:
$01000500C47(Cr)
SETPOINT STORAGE IN EEPROM MEMORY
The setpoint are stored in the RAM memory and lost upon instrument power off. It is necessary to
send a special command to save them permanently in the EEPROM memory. Please note that the
writing number allowed in the EEPROM memory is limited (about 100000).
The PC transmits
the ASCII string:
$aaMEMckckCR
Possible instrument responses:
-
correct reception:
&&aa!\ckckCR
-
