Teledyne API – Technical Manual - Model 300E Family CO Analyzers Basic Operation

6.6.3.3.RNGE  MODE  AUTO: Configuring the M300E/EM Analyzer for AUTO Range Mode

In AUTO range mode, the analyzer automatically switches the reporting range between two user-defined ranges (low and high).

∙The unit will switch from low range to high range when the CO2 concentration exceeds 98% of the low range span.

∙The unit will return from high range back to low range once both the CO2 concentration falls below 75% of the low range span.

In AUTO Range Mode the instrument reports the same data in the same range on both the A1 and A2 outputs and automatically switches both outputs between ranges as described above.

Also the RANGE test function displayed on the front panel will be replaced by two separate functions: RANGE1: The LOW range setting for all analog outputs.

RANGE2: The HIGH range setting for all analog outputs.

The high/low range status is also reported through the external, digital status bits (See Section 3.3.3). To set individual ranges press the following keystroke sequence.

Avoid accidentally setting the

range ( ) of the instrument with a higher span limit than the

range ( ).

This will cause the unit to stay in the low reporting range perpetually and defeat the function of the

range mode.

The and ranges have separate slopes and offsets for

computing the CO

concentration.

The two ranges must

be independently

calibrated.
