ANALOG
Configure Analog Output Parameters
Input: ANALOG <output>, [<bipolar enable>], [<mode>], [<input>], [<source>],
[<high value>], [<low value>], [<manual value>]
Returned: Nothing
Remarks: Configures the analog output parameters.
<output> Specifies which analog output to configure.
<bipolar enable> Specifies whether the analog output is positive output only or bipolar.
<mode> Specifies data the analog output monitors. Valid entries: 0 = off,
1 = input, 2 = manual, 3 = loop. Loop is valid only if <output> = 2 .
<input> Specifies which input to monitor if <mode> = 1 .
<source> Specifies input data. Valid entries: 1 = kelvin, 2 = Celsius,
3 = sensor units, 4 = linear equation.
<high value> If <mode> is 1 , this parameter represents the data at which the
analog output r100% output.
<low value> If <mode> is 1 , this parameter represents the data at which the analog
output reaches -100% output if bipolar, or 0% output if positive only.
<manual value> If <mode> is 2 , this parameter is the output of the analog output.
Example: ANALOG 1, 1, 2, , , , ,-25.5[term] - Sets analog output 1 to manual mode with -25.5% output
(-2.55 V).
ANALOG 2, 0, 1, A, 1, 100.0, 0.0[term] - Sets analog output 2 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: Returns the percentage of output of an analog output. <output> specifies which analog
output data to query.
BEEP
Configure System Beeper Parameters
Input: BEEP <off/on>
Returned: Nothing
Remarks: Enables or disables system beeper sound when an alarm condition is met. <off/on>
disables/enables the beeper.

Remarks: Returns system beeper parameters. See the BEEP command for parameter descriptions.
BEEPST?
Query System Beeper Status
Input: BEEPST?
Returned: <beeper status>
. Format: n[term]
Remarks: Returns the current condition of the system beeper.
