5-2-1. Introduction
In order to obtain peak performance from the EXA SC202, you must set it up for each custom applica-
tion.
*OUTP : mA output is set as default to 0-1 mS/cm or 0-19.99 M·cm.
For enhanced resolution in more stable measuring processes, it may be desirable to
select for example 5-10 S/cm range.
*HOLD : The EXA SC202 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.
*TEMP.1, 2 : First and second temperature compensation types and values. (see also section 5-2-4)
* NaCl is the default compensation and is used for neutral salt solutions. Strong solu-
tions of salts are compensated, as are process waters and pure, and ultrapure water.
* TC temperature coefficient compensation uses a linear temperature compensation
factor. This can be set by calibration or configuration.
* Matrix compensation is an extremely effective way of compensation. Choose from
standard matrix tables, or configure your own to exactly suit your process.
*SERV : This selection provides access to the service menu.
What follows are pictorial descriptions of typical frontplate pushbutton sequences for each parameter
setting function. By following the simple YES/NO prompts and arrow keys, users can navigate through
the process of setting range, hold and service functions.
