Instruction manual

Varec, Inc. 53
7532 Radar Tank Gauge
This function displays the suggested range of mapping. The reference point is always
the reference point of the measurement (see page 44). This value can be edited by the
operator.
For manual mapping, the default value is: 0 m.
Function “start mapping” (053)
This function is used to start the interference echo mapping up to the distance given in
“range of mapping” (052).
Selection:
• off — no mapping is carried out
• on— mapping is started
During the mapping process the message “record mapping” is displayed.
Caution! A mapping will be recorded only if the device is not in alarm-state.
Display “dist./meas.value” (008)
The distance measured from the reference point to the product surface and the level
calculated with the aid of the empty alignment are displayed again. Check whether the
values correspond to the actual level or the actual distance. The following cases can
occur:
• Distance correct — level correct — continue with the next function, “check
distance” (051)
• Distance correct —
level incorrect — Check “empty calibr” (005)
• Distance incorrect — level incorrect — continue with the next function, “check
distance” (051)
Function “history reset” (009)
By this function a history reset of the device is performed, i.e. the correspondence table
between level an index values is deleted. A new correspondence table will be filled and
stored after the history reset (see page 55).
