How to configure the Operational range of EchoSwitch®
Before starting, take two measurements. 1) Measure the
distance from the bottom of the sensor (transducer face) to the
bottom of the tank. This will be the HEIGHT setting. 2) Measure
the distance from the bottom of the tank to the Maximum Level
of Liquid (Full). This will be the FILL‐H setting.
1. In TOP‐LEVEL MENU mode, select TANK.
2. Select HEIGHT.
3. Using the UP and DOWN buttons, set the HEIGHT of the
tank (transducer face to the bottom of the tank).
4. To enter the value, press and hold SELECT for 2 seconds
and release. SAVED will display.
5. When FILL‐H appears, press SELECT.
6. Using the UP and DOWN buttons, set the Fill Height (FILL‐
H) of the tank (max. level of liquid to the bottom of the
tank).
7. To enter the value, press and hold SELECT for 2 seconds
and release. SAVED will display.
8. Select EXIT to return to TOP‐LEVEL MENU.
Note: The Height and Fill‐Height (Fill‐H) settings also determine the 4 to 20 mA current span. The Height
setting determines the 4mA position and the Fill‐H setting determines the 20 mA position.
Note: To speed up the scrolling of the values on the display, hold down the SELECT button while holding down
the UP or DOWN buttons.
