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.
MINIMUM RANGE:
At CALIBRATION
- 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
³12" (30.5 cm) for US2-1A1A
sensors and
³ 16" (40.6 cm) for US2-2A1B 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
³0). In
Level
or Range modes the Ultrason will only accept MinRg
values
³ 8" (20.3 cm).

MAXIMUM RANGE:
Press
È to get to
