No. The sender panels are sprayed with a protective coating for some protection.
How much power does it consume?
May 31, 2017Very little, it draws about 1/10 of an amp when operating, less than 1/100 amp when off. You can leave it turned on for a few weeks, but you should turn it off if to conserve the battery if the rig is not being used for more than a couple of months.
Can I use an under coating to protect the sender?
November 12, 2014Yes, we recommend Premium Rubberized Rocker Guard.
Does is work on other types of tanks?
May 31, 2017It has to be a plastic tank with a wall thickness of 3/4” or less, and the liquid inside must be water based. It will not work on metal propane tanks (you must use the existing LPG sensor) or on gasoline tanks.
Do I need to calibrate the display?
November 12, 2014No. The display is self-calibrated.
What does “Sht” mean?
“Sht” is displayed when the signal line is shorted to ground.
What does “StA” mean?
“StA” appears when the display is programmed for one sender panel but dual sender panels are connected to that tank.
What does “Err” mean?
“Err” stands for error. The display does not recognize the signal coming from the sender panel. It is likely from faulty wiring or damaged sender panel.
What does “OPn” mean?
“OPn” stands for open circuit, meaning the display is not communicating with the sender panel. It is most likely from an open connection or damaged sender panel.
