5-6 Parameter setting
5-2. Commissioning mode
In order to obtain peak performance from the EXA ISC202, you must set it up for each custom application.
*OUTP : mA output is set as default to 0-1000 mS/cm.
For enhanced resolution in more stable measuring processes, it may be desirable to
select for example 0-100 μS/cm range.
*HOLD : The EXA ISC202 transmitter has the ability to ‘HOLD’ the output during maintenance
periods. This parameter should be set up to hold the last measured value, or a fixed
value to suit the process (Section 5-2-2).
*TEMP.1, 2 : First/second temperature compensation types and values (see section 5-2-4 and 5-2-5).
* NaCl is used for neutral salt solutions. Strong solutions of salts are compensated, as
are process waters, pure, and ultrapure water.
* T.C. temperature coefficient compensation uses a linear temperature compensation
factor. This can be set by calibration (section 5) or configuration (service code 21).
* MATRX compensation is an extremely effective way of compensation. Choose from
standard matrix tables, or configure your own to exactly suit your process.
The default setting for *TEMP.1 and *TEMP.2 is NaCl. *TEMP.2 is enabled when it is
not equal to *TEMP.1.
*SERV : This selection provides access to the service menu.
