MODEL 54e pH/ORP			SECTION 5.0
			SOFTWARE CONFIGURATION
5.3 CHANGING OUTPUT SETPOINTS (NORMAL ONLY)
Alarm setpoints			This section describes how the 4 (or 0) to 20 mA current outputs can be
			reranged. Note that the current outputs can be configured to represent
			pH, temperature, glass impedance, or reference impedance. See
	Output setpoints
			Section 5.6 for details on configuration.
Simulated test			1. From the main menu, move the cursor down to "Program" and press
			Enter (F4). On this display, move the cursor to "Rerange outputs"
	Exit	Enter	and press Enter (F4).

Output 1

Output 2

2.Select the desired output by moving the cursor down to highlight it. When the correct output is highlighted, press Enter (F4) to get to the adjustment screen.

ExitEnter

CAUTION: Current Output 1 will be affected.

ExitEnter

3.This message asks for confirmation of the requested change. Changes in these settings may degrade process control, so use cau- tion when making changes. Press Enter (F4) to continue. Otherwise press Abort (F1).

4 mA: 0.00 pH

20 mA: 14.00 pH

Output 1: 12.00 mA

ExitEnter

4 mA: +00.00 pH

20 mA: 14.00 pH

Output 1: 12.00 mA

This screen allows changing the setpoints for output 1. A similar screen is available for output 2. The live current output now being transmitted by the controller is shown on the third line.

4.Press Edit (F4) to make changes in the setpoints. The Edit key changes to a Save key and the F3 key becomes active as an Esc key. Use the arrow keys to make the display read the desired val- ues for the high and low current output limits. When done, press Save (F4) to enter the changes into memory. Press Esc (F3) to can- cel changes.

NOTE

Outputs that have been configured as 0-20 mA in Section 5.6, will show 0 mA instead of 4 mA on the top line. Outputs that are based on temperature or impedance values will show matching units such as °C, MΩ, or kΩ. See Section 5.6 for output config- uration.
