5.8 Measurement
The Measurment menu option allows the user to program items directly affecting the measurement of Inputs.
To program the Measurement options:
From the Program menu use the UP (↑ ↑ ↑ ↑ ↑ ) or DOWN (↓ ↓ ↓ ↓ ↓ ) button to highlight Measurement and then press the ENTER
button. The Measurement menu will be displayed with two options: Span&offset and Demo Mode. Use the UP
(↑ ↑ ↑ ↑ ↑ ) or DOWN (↓ ↓ ↓ ↓ ↓ ) button to select the option you wish to program and then press the ENTER button. The options are
described in the following sections.
5.8.1 Span & Offset
The Span & Offset option allows the user to turn Span and Offset On or Off for RTD and Thermocouple point
types. This function enables Span and Offset compensation to allow for correction of known inaccuracies in
RTDs and Thermocouples.
To enable or disable Span & Offset:
From the Measurement menu, use the UP (↑ ↑ ↑ ↑ ↑ ) or DOWN (↓ ↓ ↓ ↓ ↓ ) button to highlight Span&offset and press the ENTER
button. The display will read "spnofs=YES*" or "spnofs=NO*". Press the YES button to enable Span & Offset or the
NO button to disable Span & Offset and then press the ENTER button to return to the Measurement menu.
If enabled, a Span&offset menu option will be displayed in the Point setup menu to adjust the Span and Offset
compensation values for Thermocouple and RTD point types.
5.8.2 Demo Mode
The Demo Mode option allows the user to put the Recorder in the Demo Mode of operation. In the Demo Mode,
direct inputs are ignored and calculated points use internally generated waveforms.
The Demo Mode is suited to the 1 volt scale. It is advisable to set up a sample Demo Mode and save the
configuration to disk/card. Then this configuration can be loaded anytime the Demo Mode is required.
To turn the Demo Mode On or Off:
From the Measurement menu, use the UP (↑ ↑ ↑ ↑ ↑ ) or DOWN (↓ ↓ ↓ ↓ ↓ ) button to highlight Demo Mode and press the ENTER
button. The display will read "Demo mode=YES*" or "Demo mode=NO*". Press the YES button to turn the Demo Mode
On or the NO button to turn the Demo Mode Off and then press the ENTER button to return to the Measurement menu.
NOTE: In the Demo Mode of operation, the Recorder ignores all direct inputs and uses an internal generator
for external or calculated points. Powering the unit off loses the Demo Mode.
