5.6 CHANGING OUTPUT PARAMETERS (continued)

Output Setup Parameters (for Normal Outputs)

Range: 4-20 mAl

Dampen: 0 sec

Hold: Last Value

ExitEdit

Hold: Last Value

Fixed Hold: 21.00 mA

Fault: 22.00 mA

ExitEdit

4a.	Menu Item		Options

	Range		4-20mA/0-20mA
	Dampen(ing)		0-299 sec
	Hold	Last value/fixed value
	Fixed Hold (if Output 1 hold is "fixed value")		0-22.00 mA
	Fault (fixed value in a fault condition)		0-22.00 mA

These parameters can be adjusted by highlighting the desired item and pressing the Edit 4 key. Once Edit has been pressed, change the item as needed and then press Save 4 to store the value.

"Range" determines whether the 4-20mA or 0-20 mA convention is used for the current output. If the range is changed, be sure to rerange the outputs as described in Section 5.3.

"Dampening" is used to time-average the current output, smoothing out the effect of a noisy reading. Higher values provide more smooth- ing.

Enabling the "hold" feature will give the user the option of placing the output in hold during the calibration sequence.

A "fixed value" places the held output at a fixed value between 0 and 22 mA.

Output Setup Parameters (for PID Outputs only)

Setpoint: 7.00 pH

Proportional: 100.0%

Integral: 0 sec

ExitEdit

Derivative: 0.0%

Range: 4-20 mA

Hold: Last Value

ExitEdit

4b.	Menu Item	Options
	Setpoint	-2 to 16 (pH), ±1400 mV (ORP/Redox)
		-15 to 120°C (Temp), 0-140 kΩ(Ref Imp),
		0-2000 MΩ(Glass Imp)
	Proportional	0-299.9 %
	Integral	0-2999 sec

	Derivative	0-299.9 %

The four parameters above are only available for outputs that have been configured as PID outputs in step 3. These parameters can be adjusted using the same technique as in step 4a, by highlighting the desired item and pressing the Edit 4 key. Once Edit has been pressed, change the item as needed and then press Save 4 to store the value.

Use caution in changing the values of these parameters.

"Setpoint" is usually the desired value at which the process is being controlled, typically the output will be 4(or 0) mA when the parameter is near the setpoint. This setting can also be changed using the pro- cedure in Section 5.1.
