ANALOG

Monitor Out Parameter Command
Input
ANALOG <output>,<input>,<units>,<high value>,
<low value>,<polarity>[term]
Format n,n,n,±nnnnn,±nnnnn,n
<output>
<input>
<units>
<high value> If output mode is Monitor Out , this parameter represents the data at
<low value> If output mode is Monitor Out, this parameter represents the data at
<polarity>
Example ANALOG 2,1,1,100.0,0.0,0[term] sets Output 2 Voltage mode to monitor Input A
kelvin reading with 100.0 K at +100% output (+10.0 V) and 0.0 K at 0% output (0.0 V).
Remarks Use the OUTMODE command to set the output mode to Monitor Out. The <input>
parameter in the ANALOG command is the same as the <input> parameter in the OUT-
MODE command. It is included in the ANALOG command for backward compatibility
with previous Lake Shore temperature monitors and controllers. The ANALOG com-
mand name is also named as such for backward compatibility.
ANALOG? Monitor Out Parameter Query
Input
ANALOG? <output>[term]
Format n
Returned <input>,<units>,<high value>,<low value>,<polarity>[term]
Format n,n,±nnnnn,±nnnnn,n (refer to command for definition)

ATUNE

Autotune Command
Input
ATUNE <output>,<mode>,[term]
Format n,n
<output>
<mode>
Example ATUNE 2,1 [term] initiates Autotuning of control loop associated with output 2, in
P and I mode.
Remarks If initial conditions required to Autotune the specified loop are not met, an Autotune
initialization error will occur and the Autotune process will not be performed. The
TUNEST? query can be used to check if an Autotune error occurred.

BRIGT

Display Brightness Command
Input
BRIGT <brightness value>[term]
Format n
<brightness value> 0–3
Remarks Sets the display brightness for the front panel display 0=25%, 1=50%, 2=75%,
3=100%.
Output 2 is the only valid entry and must be included (included for com-
patibility with other Lake Shore temperature instruments). 2 = Output 2
Specifies which input to monitor. 0 = none, 1 = Input A, 2 =Input B
Specifies the units on which to base the output voltage: 1 = kelvin, 2 =
Celsius, 3 = sensor units
which the Monitor Out reaches +100% output.Entered in the units
designated by the <units> parmeter. Refer to OUTMODE command.
which the analog output reaches -100% output if bipolar, or 0% output
if positive only. Entered in the units designated by the <units> parmeter.
Specifies output voltage is 0 = unipolar (positive output only) or
1 = bipolar (positive or negative output)
Specifies the output associated with the loop to be Autotuned: 1 or 2.
Specifies the Autotune mode. Valid entries: 0 = P Only, 1 = P and I,
2 = P, I, and D.
