Operation and Description of Instrument Function

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)

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.
