CHANNEL CONFIGURATION
After entering correct pass-code and selecting the blinking 'CH' (ref. SETUP section), the display shows 'SLCt CH' (for
"Select Channel"). Use ^v key to display the desired channel. Selected channel will be displayed in the format 'CHANEL
x' (where x=channel#). Once the desired channel # is displayed, push SETUP key to go on to setup parameters for the
displayed channel #.
Setup For Input Type
The display will briefly show 'IP TYPE' (for "Input type") after which the
present input type for the selected channel will be displayed. Various inputs
available are: J T/C, CR.AL T/C (Chromel Alumel, type K T/C), T T/C, E
T/C, CURRENT, or VOLTAGE. If the unit has a noble metal thermocouple
option, then only one T/C can be selected i.e. B T/C, R T/C, or S T/C. Use the ^v
key to display the desired input type. Once the desired input type is displayed,
push the SETUP key to enter that input type and go to Setup For Channel
ON/OFF.
NOTE : If you have a millivolt input unit (instead of thermocouple), the various
types of inputs selectable are CURRENT, HI VOLT (0-10Vdc input) and LO VOLT (for millivolt input).
Setup for Voltage or Current Input:
Setup For Channel ON/OFF
After selecting input type, the next parameter for configuration is Channel
ON/OFF, which determines whether a channel is scanned or not. If for any reason
a channel is not being used, it must be turned OFF. In this way the unit will not
spend any time scanning it. This will also prevent the unit from displaying a
'HELP' message on a channel that has nothing hooked up to it. Use ^v key to
select the desired setting. If a channel is OFF, the display will show 'CHx OFF' ,
and if the channel is ON the display will show 'CHx ON' (x=channel #).
Use ^v key to display the desired ON/OFF setting, and then push SETUP key to
enter that setting and go on to setup Decimal Point Position.
Setup For Decimal Point Position
After turning a channel ON or OFF, the next parameter for configuration is setting
the decimal point position. This is indicated by the display showing ' 9999' . ^v
key moves the decimal point through all the possible positions. After '9.999', the
display goes to '9999' which indicates a display with no decimal point. Use ^v key
to move the decimal point to the desired position, and then push SETUP key to
enter that setting and go to setup High Scale.
Setup For High Scale
After setting a channel's decimal point position, the next parameter to be set is Hi
Scale. This parameter determines what number will be displayed when the
transducer puts out its maximum signal. For example, suppose a pressure transducer
produces a 0Vdc to 10Vdc signal which corresponds to 0psi to 150psi. Then you
would want the display to show 150 when 10Vdc is measured. To do this, set the Hi
Scale=150.
After pushing SETUP key, the display will briefly read 'HI SCLE' (for "High
Scale"), and then show the current High Scale setting. The flashing digit is the active
digit. Pushing ^v key and keeping it pushed, will increment the digit. Releasing ^v
