ANALOG OUTPUT CALIBRATION

Analog Output Calibration Procedure:

The calibration of the

918 RTP

can be done in the following way :

Connect the following circuit to terminal pins 11 and 12, i.e Analog O/P (+) and Analog O/P (-).

LOAD

+24 VDC

+ –

Pin # 11 [Analog O/P (+)]

Pin # 12 [Analog O/P (-)]

Press the

key immediately at power-up to enter the Calibration mode.

The unit first displays

The unit then displays

Calibrate the unit for 4 mA. Use key to increase the O/P current and key

to decrease the O/P current.

Press

key and the next display is

Calibrate the unit for 20 mA. Use the same keys as stated above to increase / decrease the O/P current.

SOLDER JUMPERS

Solder pads on the unit:

The solder pads are used to select the relay settings (whether NO or NC) and the Open Collector outputs.

To make the solder pad selections follow the steps given below:
1. Remove the PBT cover from the back of the unit by removing the screws.
2. After you remove the PBT cover, you will notice solder pads on the right hand side of the PCB. (Shown in the figure above.)
3. Short the solder pads according to the output selected.
Refer to the table given below:
