Setpoint ramping status
RMPS?
Query the ramp status.
For slow ramps of the internal setpoint, the
RMPS?
query will mon-
itor the real-time status of a setpoint transition.
The response is one of the following token values:
IDLE 0
,
PENDING
1
,
RAMPING 2
,
PAUSED 3
.
RMPS?
Example:
RAMPING
Pause or continue ramping
STRT
z
Cause a setpoint ramping event in progress to pause (STOP) or con-
tinue (START).
z
=
(
STOP 0
,
START 1
).
Note that
STRT
cannot
be used to initiate a new setpoint transition
from the
RMPS
PENDING
state—this can only be accomplished by
pressing [Ramp Start
/
Stop] on the front panel.
STRT START
Example:
Manual Output
MOUT(?)
{
f
}
Set (query) the manual output value
{
to
f
}
, in volts.
The manual output can be set with millivolt resolution. Note that
setting
MOUT
does
not
modify whether the controller is in manual or
PID
control mode. For on
/
o
ff
control of manual output, see
AMAN
.
The allowed range for
MOUT
is
−
10
.
000
≤
MOUT
≤
+
10
.
000.
MOUT?
Example:
+8.000
Upper Output Limit
ULIM(?)
{
f
}
Set (query) the upper output limit
{
to
f
}
, in volts.
The upper limit can be set with 10 mV resolution. Note that, re-
gardless of the operating mode of the SIM960 (see
AMAN
), the out-
put voltage will always be clamped to remain less positive than the
ULIM
limit. Combined with the
LLIM
limit, this results in the output
obeying:
−
10
.
