Omega DPS3100 Setup For Relay Latch/Non-Latch, Setup for Buzzer, Setup For Channel Calibration

Setup For Relay Latch/Non-Latch

After setting DISPLAY TIME, the next parameter determines whether the output relays will operate in a Latched or Non- Latched mode.

Relay Latched Mode:

In this mode the relay is activated when its LIMIT value is exceeded and stays activated until the operator manually resets the relay. To manually reset a channel relay, use CH. SEL key to step to the desired channel number, and while keeping the CH. SEL key pressed, simultaneously press the RESET key.

Relay Non-Latched Mode:

In this mode the relay is activated when its LIMIT value is exceeded. The relay is deactivated when the channel reading drops below the LIMIT value by the DEADBAND setting.

The display will show 'NON LCH' for Non-Latch mode, or 'LAtCH' for Latch mode. Use ^v key to toggle between settings. Once the desired setting is displayed, push SETUP key to enter that value and go to Setup For Cold Junction Calibration.

Setup for Buzzer

The next step turns the buzzer on or off. Turning on the buzzer provides an audio alarm when ever any limit gets activated. Display format is 'ALr On' (for 'alarm on') or 'ALr OFF' (for 'alarm off'). Push ^v key to select desired mode. After completing the selection, push SETUP key to go to next step.

Setup For Cold Junction Calibration

After setting Relay Latch/Non-Latch, the next parameter is the cold junction reference temperature. The display will first show 'COLd JN' , and then the cold junction temperature will be indicated. Use the ^v key to adjust until the display reads the proper temperature. Once the correct temperature is displayed, push the SETUP key to enter that setting and go to Setup For Channel Calibration.

NOTE 1: The unit must be powered up for at least ten minutes before adjustments are made to cold junction reading.

NOTE 2: Press CH. SEL key to see the Cold Junction reading directly in millivolts.

Setup For Channel Calibration

After setting the Cold Junction Reference temperature, the next step is a display of channels for calibration purposes. This allows easy calibration of each channel without the instrument scanning to the next channel. The display will show the channel input reading in the form 'x-nnnnn'where x=channel # and nnnnn is the channel reading.

NOTE: ONLY channels that are turned ON will be displayed at this time!

Press SETUP key to step the display to the next channel.

Input Range Setup (for current and voltage):

Voltage Range Setup (0-10vdc)

After all the enabled channels have been displayed, the VOLTAGE range may be setup. The display will briefly show 'U rAnGE' (for "Voltage Range")

followed by the current setting. Use ^v key (ref. Setup For High Scale) to set the desired VOLTAGE value. Once the
