Returns the present value of the voltage and current limits (reset values shown).
LOCAL
Overlapped Coupled IEEE-488 RS-232 Sequential
x x x x x
(Local command) Puts the Calibrator into the local state, clearing the remote state (see
the
REMOTE
command) and front panel lockout (see the
LOCKOUT
command). This
command duplicates the IEEE-488 GTL (Go To Local) message.
Parameter: (None)
Example:
LOCAL
Set the instrument into the local state, clearing the remote state and front panel lockout (if
enable).
LOCKOUT
Overlapped Coupled IEEE-488 RS-232 Sequential
x x x x x
(Lockout command) Puts the Calibrator into the lockout state when in remote control
(see the
REMOTE
command). This means no local operation at the front panel is allowed
during remote control. To clear the lockout condition, use the
LOCAL
command. This
command duplicates the IEEE-488 LLO (Local Lockout) message.
Parameter: (None)
Example:
LOCKOUT
Set the instrument into the front panel lockout state. The front panels controls cannot be
used.
LOWS
Overlapped Coupled IEEE-488 RS-232 Sequential
x x x x x
(Low Potential Output Terminals command) Selects whether or not the Calibrator front
panel NORMAL LO terminal and AUX LO terminal are internally tied together (default)
or are open. This feature is used for ac power, dc power, dual dc volts and dual ac volts
outputs. Once set, the Calibrator retains the LO setting until power off or reset.
Parameter:
OPEN
(disconnect NORMAL LO and AUX LO terminals)
TIED
(connect NORMAL LO and AUX LO terminals)
Example:
LOWS TIED
Tie the front panel NORMAL LO and AUX LO terminals together.
LOWS?
Sequential Overlapped Coupled IEEE-488 RS-232
x x x x
x
(Low Potential Output Terminals query) Returns whether or not the Calibrator front
panel NORMAL LO terminal and AUX LO terminal are internally tied together (default)
or are open.
Response:
OPEN
(disconnected NORMAL LO and AUX LO terminals)
TIED
(connected NORMAL LO and AUX LO terminals)
Example:
LOWS?
returns
OPEN
Returns
OPEN
when the Calibrator front panel NORMAL LO and AUX LO terminals are
not tied together.
