Operation and Description of Instrument Function	Average Temperature/Water Bottom Sensor and Converter

VH82 Element Number

Item type: read and write

Default: 2

Range: 1 ~ 6

Number of available temperature elements.

Do not change the default parameter on the 4532 ATC. The number of elements on this version is pre-determined by the customer's choice. It may cause faulty calculation or an inappropriate error display.

VH83 No. of Preambles

Item type: read and write

Default: 5

Range: 2 ~ 20

Number of preambles for HART communication.

VH84 Distance Unit

Item type: select

Default: mm

Selection: ft., m, inch, mm

Selection of level display unit. It applies to liquid level display on VH02 "Liquid Level". Level units are coded based on universal HART setting, ft. (HART code: 44), m (HART code: 45), inch (HART code: 47), mm (HART code: 49).

VH85 Kind of Interval

Item type: select

Default: Even Interval

Selection: Even Interval (always "Even" for 4532 ATC)

Selection of element interval depending on spacing layout.

Caution! Do not change this parameter on the 4539 ATC Converter + Temperature version unless repairing. The type of Interval and individual element positions are physically determined at factory.

VH86 Bottom Point

Item type: read and write

Default: 500mm

Range: 0mm ~ 99999mm

Position of #1 element. The #1 element position becomes critically important when "Even Interval" is selected at VH85 because remaining element positions rely on the location of the Bottom Point.
