TM-XR9B-01XN 3–11
FOLD? Asks for the supply’s present foldback setting.
Response: FOLD <mode> where mode is:
0 (OFF) or
1 (CV or Constant Voltage mode) or
2 (CC or Constant Current mode)
GTL Go to local. Returns the power supply to local control. See LLO (Local Lockout).
See also“Remote/Local Operation” on page 2–20.
HOLD <1/ON>,
<0/OFF>
Enables or disables voltage/current setting hold mode for the supply. When
HOLD ON is specified, hold mode is enabled so that all voltage and current
settings which would normally be implemented by the supply are held until a TRG
(trigger) command is received. This feature allows you to synchronize the
operation of several supplies.
Initial value: HOLD OFF or HOLD 0
HOLD? Asks for the present hold mode setting.
Response: HOLD 0 (OFF or disabled) or HOLD 1 (ON or enabled)
ID? Asks for the power supply model and the master EPROM version.
Response: ID <model name><version>
IDATA
<Ilo>,<Ihi>
Calculates and records the slope and offset for programmed current using ILO and
IHI data. Set CMODE ON before using this command. See also the calibration
procedures in Chapter 4.
<Ilo> and <Ihi> are in <current> format.
IHI In response to this command, the power supply sends a programmed current value
to the output terminal. This value is at the high end of the power supply’s current
range and is read by an external device connected as part of the calibration
procedure. Refer to this value as IHI and record it to use as input with the IDATA
command. Set CMODE ON before using this command. See also the calibration
procedures in Chapter 4.
ILO In response to this command, the power supply sends a programmed current value
to the output terminal. This value is at the low end of the power supply’s current
range and is read by an external device connected as part of the calibration
procedure. Refer to this value as ILO and record it to use as input with the IDATA
command. Set CMODE ON before using this command. See also the calibration
procedures in Chapter 4 .
