SLT 5.0 Level and Flow Monitor
CALIBRATION
- for Level/Inventory Applications
1. Before starting the calibration determine:
a)
MAX RANGE = ________________ (Maximum
range = distance from Sensor to Zerolevel)
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)
When liquid is at zero level press

to view the Range reading in the
Status menu. Use this range measured by the SLT 5.0 as the Max Range
setting.
or
b) Carefully measure distance from sensor to zero level with a tape measure,
and use this measurement as the Max Range setting.
MINIMUM RANGE:
At CALIBRATION
- Press

to get to Min Range
- Press

to move the cursor under the digits
- Use

or

to set the minimum range
Note : Min Range must be at least 12" (30.5 cm) for PZ32T sensors, 16" (40.6 cm)
for PZ52T and PZ34 sensors and 8" for PZ15 sensors. For correct tank volume
calculation in Hrt mode Min Range must be the actual distance from the end of
the sensor to the top of the tank.
MAXIMUM RANGE:
Press

to get to Max Range
Enter Max Range determined above.
