MODEL 54e pH/ORP SECTION 5.0
SOFTWARE CONFIGURATION
5.6 CHANGING OUTPUT PARAMETERS
This section describes the options available for configuration of the out-
puts. Each output can be configured to represent pH (or ORP/Redox, see
Appendix A), temperature, glass impedance, or reference impedance. In
addition, each output can be linear (normal) or nonlinear (PID). Several
options for both modes of outputs can be configured. This section
describes the features and shows how to make modifications in the set-
tings.
1. Beginning from the main menu, move the cursor down to "Program"
and press Enter 4. From the program menu, move the cursor down
using the arrow key b to highlight "Configure" and press Enter 4.
Use the arrow key again to highlight "Outputs" (as shown on the left)
and press Enter 4.
2. There are 5 menu headers that relate to outputs. Each output has a
control header and a setup header. In addition, the hold feature is
turned on here. The hold feature is mostly used to prevent upsets dur-
ing buffer calibration of the pH sensor.
To access each header, highlight the desired item and press the Enter
4 key. To select another header, use the arrow keys. The bottom
menu header will only be highlighted if the end of the menu has been
reached.
NOTE
Always configure the control parameters BEFORE mak-
ing changes in the output setup. Changes in the output
setup in step 4 will depend on the options that have been
selected in step 3.
3. Menu Item Options
Output Measurement Process/Temperature/Ref
Impedance/Glass Impedance
Control Mode Normal/PID
Each output can be configured with the options above. The default
options are that output 1 is Process (pH or ORP/Redox), output 2 is
Temperature and that both outputs are Normal (not PID). This is the
most common configuration and may not require changes. If no
changes are desired, skip to step 4.
To make changes in these parameters, highlight the desired menu
header and press Enter 4. The value now being used is displayed
and the F4 key can be pressed to Edit the item. Once Edit has been
pressed, change the item as needed and then press Save 4 to
store the value. Repeat for the other output and/or items as needed.
