5.4.8 VGET

Syntax

<address>VGET:<var_index><CR>

Description

Returns value of an internal configuration variable (VAR.)

Data Parameters Sent

var_index is index number for internal VAR as follows:

Var	Name	Description		Allowable Range
Index
0	analog_range	Full-Scale concentration	5.0 – 400.0 (Units are
		range for Analog Output	current unit of measure,
		scaling	wt% or g/Nm3)
1	azero_enable	Auto-Zero Enable VAR.	0	= Off
		(only valid if Auto-Zero	1	= On
		hardware is installed)
2	azero_period	Period for Auto-Zero	5.0 - 86400.0 Seconds
		Calibration timer
3	carrier_weight	Mol weight of carrier gas	27.0 – 32.0 mol weight
		for wt% calculations (32.0
		= O2)
4	comm_mode	Not Used	N/A
5	iir_filt	Digital Concentration	0.05 – 1.0
		filter	(1.0 = No Filtering, lower
			values increases filtering)
6	conc_units	O3 Concentration	0	= wt%
		measurement units	1	= g/Nm3

Response

<address>:<var_value>#<checksum><CR>
