The channel numbers in Display Option #6 start with 'CH1 dIF' and go up to 'CH7 dIF' (CH4 dIF for 4 channel units).
Following this the display jumps back to Option #1 (elapsed time), and the cycle is repeated.
Setup For Display Time
The next parameter to be set is DISPLAY TIME. This determines the number
of seconds a channel's reading is displayed before moving to the next channel.
The display will first show 'dSPLy t' (for Display Time), and then the current
setting in seconds. Use
DIG
key (ref. Setup For High Scale) to set the
desired DISPLAY TIME. Once the desired DISPLAY TIME value is displayed,
push SETUP key to enter that value and go to setup Relay as Latching or Non-
Latching.
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
DIG
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 whenever any limit gets activated. Display format is 'ALr On' (for 'alarm
on') or 'ALr OFF' (for 'alarm off'). Push
DIG
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
DIG
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.
