STANDARD for all other systems.

 

Cell: Standard

1>

For STANDARD sensors: Select from these options: 0.01, 0.1, 1.0, 10.0 or 20.0.

Cell: Custom

1.0000 >

For CUSTOM sensors: Enter the precise cell constant from the certificate provided with your sensor, or from the information label on the sensor.

Cond Units:

uS >

Select from the following options: S, mS, k, M, PPM

PPM Factor:

2.00>

If the Units selection is PPM, you can set the ratio of Total Dissolved Solids to S. See section 3 of this manual for additional information. The TDS factor can only be set in PPM.

Options available are High, Low or proportional Pulse.

The signal may be disabled (Off) if not in use.

 

 

 

 

 

 

Output1 Setpnt:

 

In Low or High Mode, this Open Collector output will be activated when the process reaches

reach the maximum rate. Be sure to modify this setting if you change the Cond. Units.

 

 

 

 

Output1 PlsRate:

 

120 Pulses/Min

>

In Pulse mode, set the maximum rate for the proportional Pulse output. The transmitter will accept any value from 0 to 400.

Last CAL:

06-30-01 >

Use this “note pad” to record important dates, such as annual recertification or scheduled maintenance.

Settings will repeat for Loop 2 and Output 2.
