Two-Point User Calibration Sequence Example

NOTE Before performing a Two-Point User Calibration, a separate Zero Calibration must be

performed ﬁrst. It is also recommended that both calibrations be performed at 75ºF in

order to maintain accuracy over the Module’s operating temperature range.

Seq Host Module Description

1 <Q7F0> Host sends Unprotect command.

<q7F0> Module responds to command from host

2 <Lmmd-

dyyyy>

Host sends calibration date.

<S6324>

<S6302>

<S6X03>

<S6321>

<S6323>

Module responds with status -

Calibration ready for next step

, or

if date is invalid, response is

Invalid Data

, or

if not in unprotected measurement or autorun mode, response is

Invalid

Operation

(use <Q7F0>), or

if previous calibration is active, response is

Cal. Already in Progress

, or

if the LC101 had been operating for < 5 min., response is

Cal. Low Run

Time

3 <Gxx> Host sends span gas value (in percent).

<S6324>

<S6302>

<S6X03>

<S6322>

<S6328>

Module responds with status -

Calibration ready for next step

, or

if span gas value is invalid, response is

Invalid Data

, or

if not in unprotected measurement or autorun mode, response is

Invalid

Operation

(use <Q7F0>), or

if a calibration had not been started, response is

Cal. Not in Progress

, or

if the calibration has exceeded its maximum time allowed, response is

Unable to Perform Cal., Missing Parameters

4 <C10> Host sends

Sample

CO2 Zero Gas

command.

<S6325>

<S6X03>

<S6322>

<S6328>

Module responds with status -

Calibration in Progress

, or

if not in unprotected measurement or autorun mode, response is

Invalid

Operation

(use <Q7F0>), or

if a calibration had not been started, response is

Cal. Not in Progress

, or

if the calibration has exceeded its maximum time allowed, response is

Unable to Perform Cal., Missing Parameters

5 <C00> Host polls for completion of sampling.

<S6325>

<S6324>

<S6328>

<S6329>

Module responds with status -

Calibration in Progress

. Repeat this

step until a response other than <S6325> is returned.

Module responds with status -

Calibration ready for next step

, or

if the calibration has exceeded its maximum time allowed, response is

Unable to Perform Cal., Missing Parameters

, or

if acquiring data does not meet speciﬁcations, response is

Unable to

Perform Cal., Data Error.
