4532 Operation and Description of Instrument Function
VH73: "Temperature X" = raw element temperature x span (VH72) + zero offset
(VH71)
VH73 Temperature X
Item type: read only
Specified element temperature selected at VH70. The displayed value is also indicated
at individual element temperature at VH10 ~ VH25. The value is calculated based on
formula indicated on above VH72.
VH74 Position X
Item type: read and write
Range: 0mm ~ 99999mm
The position of the element specified at VH70. The position of each element is entered
when "Not Even" element spacing is selected at VH85.
VH75 Resistance X
Item type: read only
The display of the specified element resistance selected at VH70.
VH76 Resistance Adj.
Item type: read and write
Default: 0
Range: -1000.0 ~ 1000.0
Adjustment of specified element resistance at VH70. Minor resistance adjustment can
be applied on the reading value.
Note! e.g. If selected element #5 indicates 100.3 Ohm, and reference precision resistor
indicates 100.0 Ohm at the same environmental condition, then set "-0.3" in this
matrix. #5 element now has constant artificial -0.3
°C offset resistance based on raw
measurement.
VH77 Element Type
Item type: select
Selection: Pt100 (must be selected in 4532 ATC)
Note! The 4532 ATC always consists of "Pt100" elements with "Spot" element layout. Do
not attempt to change these parameters.
VH78 Average Number
Item type: read and write
Default: 1
Range: 1 ~ 10
Number of samples for calculating the average temperature. Increasing this parameter
will prevent erratic changes in the calculated value.
Caution! Additional sampling # will cause slower reaction time on value switch over. Maxi-
mum 1 sampling sequence will take approximately 2 sec. {total 11 elements (6 temp
elements and 5 times for 3 reference resistors)}
