Software Actions

	Action	Notes
1	Read light intensity value.	Note calibration unit translation stage has to move detector into beam first. Value reported as telemetry (see below)
2

Required Adjustable Settings

NOTE: device automatically switches from “LOCAL” to “REMOTE” mode when it receives a remote command through either the USB, RS-232C, or IEEE 488 GPIB interfaces.

Setting	When Needed			Notes
	Build	Observing	Maintenance
Set offset subtraction				Equivalent to “ZERO” button on device. Default should be ‘Z0’ (no offset subtraction).
Set calibration wavelength				Equivalent to wavelength buttons on device. Default value should be 658 nm. Remote command might be 'W0658'.
Set attenuator mode				“ATTN” button on device. Default should be set to ‘off’ (i.e. no attenuator in place). Remote command is ‘A0’
Set measurement units				Equivalent to “UNITS” button on device. Default should be Watts (remote command ‘U1').
Set averaging mode				Equivalent to “AVG” button on device. Default should be set to ‘Fast’ mode (no averaging by device). Remote command for ‘Fast’ mode is ‘F3’.
Set audible beep on/off				Equivalent to “BEEP” button on device. Default should be ‘off’ (remote command ‘B0’)
Set automatic range				Equivalent to “AUTO” range on device. Default should be auto-range (remote command R0).
Turn display on/off				Default should be ‘off’ (remote command ‘K0’).
Local lockout				Default should be ‘locked’ while under remote operation (remote command ‘L1’)
