Instruction manual

Varec, Inc. 45

7532 Radar Tank Gauge

Caution! To successfully commission a precise measurement to the nearest mm,

it is important you carry out a history reset on first installation after mechanical

installation and after the basic setup of the device (see page 53). Only after a

history reset the mounting calibration is carried out. Enter the measurement offset

as the first point in the dip table for the mounting calibration. When a value is

dipped at a later date, make a second entry into the dip table, using the semi-

automatic mode. This way, you can easily carry out a linear correction of the

measurement.

When configuring the function in “basic setup” (00), please take into account the

following notes:

• Select the functions as described in the “Quick Operation Guide” on page 31.

• Some functions can only be used depending on the parameterization of the device.

For example, the pipe diameter of a stilling well can only be entered if “stilling well”

was selected beforehand in the “tank shape” (002) function.

• Certain functions (e.g. starting an interference echo mapping (053)) prompt you to

confirm your data entries. Press to select “YES” and press to confirm.

The function is now started.

• If you do not press a key during a configurable time period (» function group

“display” (09)), an automatic return is made to the home position (measured value

display).

Note

• The device continues to measure while data entry is in progress, i.e. the current

measured values are output via the signal outputs in the normal way.

• If the envelope curve mode is active on the display, the measured values are

updated in a slower cycle time. Thus, it is advisable to leave the envelope curve

mode after the measuring point has been optimized.

• If the power supply fails, all preset and parameterized values remain safely

stored in the EEPROM.

• All functions are described in detail, as is the overview of the operating menu

itself, in the manual “IOM117 - Description of Instrument Functions”.

• The default values of the parameters are typed in boldface.
