4532 Operation and Description of Instrument Function
8.1.6 WB primary and Advanced temp: VH50 ~ VH59
VH53 Element Point
Item type: select
Default: 0
Selection: 0 ~ 15 (element #1 = 0, element #6 = 5)
Select element number for "Advanced" average calculation at VH26. Selected element
position will be displayed on VH54 "Element Position" and allow modification of the
volume factor at VH55 "Element Volume" for the specified element.
VH54 Element Position
Item type: read only
Range: 0m ~ 99999mm
A display of selected element position on VH53.
VH55 Element Volume
Item type: read and write
Range: 1 ~ 99999.9
For the selected element at VH53 "Element Point", extra volume can be added to the
specified element for advanced average temperature calculation. (For details, refer to
the description of VH26 "Select Average Method" on page 30)
8.1.7 WB Adjustment and Operation Power: VH60 ~ VH69
VH67 Common Voltage
Item type: read only
Range: 0 ~ 255 (0 ~ 3V)
A display of temperature element line (both signal and common) running voltage. The
detected voltage across the common line (between 0 ~ 3V) is converted to a range of
0 ~ 255 counts when it is displayed.
VH68 Output Current
Item type: read and write
Default: 16000 at 6mA
Range: 0 ~ 65536
Adjustment of 4532 ATC current consumption. In order to prevent current over-shoot
within the multidrop HART loop, this function limits the 4532 ATC power consumption
based on the set parameter. Normally, the 4532 ATC requires 6 mA or less current. Use
a tester to check the current flow in the loop. Reducing this parameter makes the
4532 ATC use less current.
