ALARM? Input Alarm Parameter Query
Input
ALARM? <input>[term]
Format a
<input>
A - D (D1 - D5 for 3062 option)
Returned <off/on>,<high value>,<low value>,<deadband>,<latch enable>,<audible>,<visible>
[term]
Format n,±nnnnnn,±nnnnnn,n,n,n (refer to command for description)
ALARMST? Input Alarm Status Query
Input
ALARMST? <input>[term]
Format a
<input>
A - D (D1 - D5 for 3062 option)
Returned <high state>,<low state>[term]
Format n,n
<high state> 0 = Off, 1 = On
<low state> 0 = Off, 1 = On
ALMRST Reset Alarm Status Command
Input
ALMRST[term]
Remarks Clears both the high and low status of all alarms, including latching alarms.
ANALOG Monitor Out Parameter Command
Input
ANALOG <output>,<input>,<units>,
<high value>,<low value>,<polarity>[term]
Format n,n,n,±nnnnn,±nnnnn,n
<output>
Unpowered analog output to configure: 3 or 4
<input> Specifies which input to monitor. 0 = none, 1 = Input A, 2 =Input B,

3 = Input C, 4 = Input D (5 = Input D2, 6 = Input D3, 7 = Input D4,

8 = Input D5 for 3062 option)
<units> Specifies the units on which to base the output voltage: 1 = kelvin, 2 =

Celsius, 3 = sensor units
<high value> If output mode is Monitor Out , this parameter represents the data at

which the Monitor Out r100% output.Entered in the units

designated by the <units> parmeter. Refer to OUTMODE command.
<low value> If output mode is Monitor Out, this parameter represents the data at

which the analog output reaches -100% output if bipolar, or 0% output

if positive only. Entered in the units designated by the <units> parmeter.
<polarity> Specifies output voltage is 0 = unipolar (positive output only) or

1 = bipolar (positive or negative output)
Example ANALOG 4,1,1,100.0,0.0,0[term] —sets output 4 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.
