4532 Operating
GVH447: Reference Zero
Indication of the converted 100 Ohm reference resistor deviation value compared to the
actual inserted element value in the temperature probe. The reading value of reference
resistor and its deviation are continuously monitored during operation to prevent from
performing an incorrect calculation. Indicated tolerance should be within ±0.15°C
(±0.27°F) depending on element characteristics, e.g. Pt100 elements have 100 Ohm
resistance at 0°C (32°F); therefore, the reading value should be within 0°C±0.15°C
(32°F±0.27°F) or less.
GVH449: Reference 150
Indication of the converted 200 Ohm reference resistor deviation value compared to the
actual inserted element value in the temperature probe. The reading value of reference
resistor and its deviation are continuously monitored during operation to prevent from
performing an incorrect calculation. Indicated tolerance should be within ±0.15°C
(±0.27°F) depending on element characteristics.
GVH450~459; Temp No.1~10
The temperature reading value from each inserted element in the probe. The reading
element temperature above 11~16 must be selected at the GVH470 "Select Point", then
the read value at the GVH473 "Element Temp."
GVH460~49; Element Position No.11~16 (not available with 4532 ATC)
GVH470: Select Point
A matrix to select the desired element data on GVH471 "Zero Adjust", GVH473 "Element
Temp" and GVH474 "Element Position."
GVH480: Diagnostic
Display of error code message. Please refer to the error code chart in
Chapter 9, Maintenance.
GVH482: Total No. Element
Enter the number of installed temperature elements in the average temperature probe.
GVH485: Type of Interval
Select type of element interval.
Even: Element spacing will be equally spaced by providing the distance at GVH487
"Element Interval", and the lowest element position can be set at GVH486 "Bottom Point."
GVH486: Bottom Point
The lowest inserted element position in the average temperature probe.
Note! This parameter setting is only used to change the theoretical element position within
the 4532 ATC's software for average calculation purposes. If does not effect the
physical location of the temperature element position.
