• High Limit - Available when Range is User Defined. Select and enter the high limit
value.
• Lower Limit - Available when Range is User Defined. Select and enter the lower limit
value.
• RT Type - Only available when Type is set to RT (Resistance Thermometer). Select this
for a list of available RT types.
• Burnout Type - Only available when Type is set to TC (Thermocouple). Toggle
between Active and Passive. Active means it will send out a current to the TC. Set to
Passive means it takes a reading without sending out a current. The T/C is wired differ-
ently for Active and Passive Burnout (see
page 19
). (Active Burnout is not available for the
Active burnout is an implementation of thermocouple health and provides error warning
messages for a range of thermocouple activity/failure conditions. Passive burnout does
not provide any error warning messages.
If the thermocouple wiring changes and the channel is set to Active, select Passive and
Commit the change. Then return to the menu and select Active and Commit the change
to update burnout settings.
• Show Burnout - Only available when Type is set to TC. Toggle between Upscale and
Downscale Burnout.
• TC Type - Only available when Type is set to TC. Select this for a list of available TC
types.
• CJ Comp - Only available when Type is set to TC. Select this for a list of available CJ
"Thermocouple CJC Compensation" on page 248.
Compensation. See
• • Int Automatic - Uses the cold junction sensor in the recorder as a variable ref-
erence temperature
• • Ext 0 Deg C - Assumes the cold junction is held at 0
ence, external to the recorder
• • Ext with Spec Temp - Uses a reference junction held at a constant tempera-
ture. Specify the temperature that the cold junction sensor is to be set at.
• • Ext Input - Use a thermocouple or resistance thermometer from another chan-
nel to measure the cold junction sensor
• External Input - Only available when CJ Compensation is set to Ext Input. Select the
input required as an external input.
• Eng. Span - (Ohms, Volts and Amps only). Only available when not using "Use Pen
Scale" option. This is the highest value of the engineering range and corresponds to the
top of the input range. Select and enter a value using the on-screen keyboard.
• Eng. Zero - (Ohms, Volts and Amps only). Only available when not using "Use Pen
Scale" option. This is the bottom of the engineering scale and represents the bottom of
the input scale. Select and enter a value using the on-screen keyboard.
• Demo Setup - Only available if there is no Analogue Input card fitted. Examples of var-
ious inputs are available without having an actual signal input coming into the recorder.
• • Demo Type - Select this for a list of available Demo Type inputs.
• • Cycle Time - Enter the Cycle Time, in seconds, of the Demo Input. Select and
use the on-screen keyboard.
• • Add Noise - This is to Add Noise to the Demo Input as a percentage value.
Select and use the on-screen keyboard.
