Teledyne 100AH instruction manual Range Menu, Single Range

Teledyne API Model 100AH SO2 Analyzer Instruction Manual, 02417, Rev. D

5.3.4 Range Menu

The instrument operates on any full scale range from 10 to 5000 PPM. The range is the concentration value that equals the maximum current (or voltage) output on the rear panel of the instrument.

If the range you select is between 10 and 500 PPM the front panel display will read the concentration anywhere from 0 to 500 PPM regardless of the range selected, however the analog output is scaled for the range selected. If the range selected is from 501 to 5000 PPM the front panel display will read from 0 to 5,000 PPM. The M100AH has 2 internal hardware gain settings, namely 0-500 PPM (gain of 10) and 0-5000 PPM (gain of 1). If the physical gain changes, then the test measurement readings such as PMT and OFFSET will be adjusted accordingly.

NOTE

If the instrument will be used on more than one range such as AUTO RANGE or DUAL RANGE, it should be calibrated separately on each applicable range (see Section 8.6 for calibration procedure).

Each 4-20 mA current output channel should be connected to one interfacing device only.

There are 3 range choices: only one of the following range choices can be active at any one time.

1.Single Range; two analog outputs are fixed to a single range.

2.Auto Range; both analog outputs are automatically set for low or high range.

3.Dual Ranges; each of an analog output ranges can be set differently.

5.3.4.1 Single Range

This range option selects a single range for both output channels (REC, DAS) of the M100AH. To select Single Range press SETUP-RNGE-MODE-SING, then press ENTR. To set the value for the range press SETUP-RNGE-SET, and enter the full scale range desired from 10 PPM to 5000 PPM, then press ENTR.
