20 Most Recent Topcon Rlh3a Long Range Rotating Laser Level Questions & Answers

Sound like the laser diode is failing. It's power is likely just strong enough to get the level position right, then dims as it runs. The unit, no longer seeing the laser, decides it's out of level and stops. Or the oil in the compensator is leaking, and the same process is happening. Unfortunately the replacement part is not economical to replace.

This is not a battery problem. It likely levels to the back corner, then to the front corner then roughly back to the middle and spins at about 150 rpm and the lights on the front blink. There are a couple things that can cause this. the most common is the the compensator cant find the laser. 5 screws hold the main housing on to the base. Remove the housing and inspect. if the internals are coated in oil, then the unit is done. The replacement part is too expensive. If the inside is dry, there is a small circuit board on the left side of the metal compensator frame. Resolder the pins in the board, and the connector going to the side board, located on the main board. about 30% of the time, this will get the laser running again. If not, the laser diode is likely dead, and it's not repairable.

If it came from alkaline batteries (Duracells, etc) flush the battery compartment with an acidic cleaner, like an orange cleaner. This will help neutralize the alkaline left behind. Clean that out as best you can. Dont put too much in the battery compartment or it will contaminate the laser internals. Clean the battery contacts, and you should be good to go. if not, then likely the main board has been damaged, and you should get it looked at. They can usually be cleaned up, but it may require a new board.

No one will tell you exactly. There could be several variants, you have to disassemble the device and look at it. Maybe there is something wrong with the circuit board, or with the contacts, or the laser transmitter has burned out and needs to be replaced.

There are 2 small screws holding the rotating head motor in place. Likely you just need to loosen these screws, and adjust the motor position and retighten.

Same exact features, buttons and functions as this manual by Irwin.

I want to use an old sensor forgiven during 30 years. I have no more manual, off course. Thanks for your answer

Most moisture meters measure the moisture content of wood or concrete is measured in percentages. So if the reading says 15 that means that there is a content of 15% moisture in the concrete.

Pressing the - (minus) button on the back toggles temperature units. Pressing + (plus) toggles barometric pressure units.

It's possible that one of the newer sensors could work in place of your 1457 sensor, but it depends on the specifications of the newer sensors and the compatibility with your base unit. The I MAX1457 sensor, which is a highly integrated analog-sensor signal processor optimized for piezoresistive sensor calibration and compensation. However, I have no information about its compatibility. If you're looking for a replacement sensor, I suggest contacting the manufacturer of your base unit to inquire about compatible sensors. Alternatively, you can check the user manual of your base unit to see if it lists compatible sensors. Garage door opener sensors are not universal. Safety sensors can only communicate with garage door openers from the same brand.

Unlikely unless you know the secret maker name and can find them in China. At the moment, no one has heard of it apart from here on Fixya. All questions need FULL 'make model (what it is)' please. https://www.google.com/search?q=dse+z111 ..
