CALIBRATION
- for Level/Inventory Applications
1. Before starting the calibration determine:
a)
MAX RANGE = ________________
(Maximum range = distance from Sensor to Zero
level)
b)
MAX LEVEL = ________________
(Maximum level of product being measured)
c)
MIN RANGE = ________________
(Distance from sensor to Max Level)
Minimum range = MAX RANGE - MAX LEVEL
(must be at least 8" / 203 mm depending on sensor
model)
2. Check the maximum range with the sensor installed by:
a)
Use
Æ
to get to UNITS/MODE then
È
to get to
Range, then Store?
Æ
Yes
(NOTE: liquid must be at zero level)
or
b)
Carefully measure distance from sensor to zero
level with tape measure.

- Press
È
to get to MinRg
- Press
Æ
to move the cursor under the digits
- Use
È
or
Ç
to set the minimum range
Note
: MinRg must be 12" (30.5 cm) for PZ32T sensors and
16" (40.6 cm) for PZ52T sensors except in Hrt mode. For
correct tank volume calculation in Hrt mode MinRg must
be the actual distance from the end of the sensor to the top
of the tank (any value 0). In Level or Range modes the
SLT32 will only accept MinRg values 8" (20.3 cm).

MAXIMUM RANGE:
Press
È
to get to MaxRg
Repeat as for MinRg
