Protection: Safeguards electrical connections from environmental and mechanical damage. Organization: Provides a central point for managing electrical wiring connections, making maintenance easier. Safety: Reduces the risk of short circuits, fire hazards, or electrical shocks by containing and insulating connections. Signal Calibration: In sensor systems, potentiometers are used to fine-tune signal levels for calibration, ensuring the sensors operate within desired ranges. Adjusting Output: It may regulate output voltage or current in circuits, allowing customization of electrical parameters to match system requirements. Balancing Circuits: Potentiometers can balance circuits or adjust offsets in control systems, ensuring stable and accurate operation. Thanks, Anthony

Tal vez necesites conectarlo porque la batería está descargada. Intenta calibrarlo nuevamente. Si no funciona, es posible que tengas que abrir la parte trasera y desconectar los cables de la batería.

If the indicator is 10+ years old then you would need to use 10% of capacity to calibrate. If newer than that check the wiring in the platform. There is video on channel on how to fix floor scale. Follow cable to junction box in platform and open that up. Check wiring in there. Might be a wire loose or in wrong order. They should all be in the same order. Thanks, Anthony

Did you make sure you put weight during the adload on the screen. If you did correctly try 1 more time. If that doesn't work you might have a problem with your OP902. You would need to replace the indicator with a new indicator like our OP909. They are $165 + tax + shipping. You can email sales@optimascale.com to purchase. Typically these OP902 have problems like this after a couple years. Thanks, Anthony

You might need to check the indicator settings to ensure it is set to continuous and that the correct baud rate is selected. If the settings are correct, you may need a null modem cable, as pins 2 and 3 are swapped. However, if you are already using a null modem cable, try switching to a regular (non-null modem) cable. Alternatively, you can purchase a DB9 null modem adapter (male to female). The female end plugs into the DB9 male connector of the cable, which then connects to the indicator. This will also swap pins 2 and 3. Pin 2 is TX (Transmit), and Pin 3 is RX (Receive) on the DB9 connector. These items are readily available on Amazon. If none of this works, there might be an issue with the internal board. Finding the correct cables and null modem adapters can be tricky. Thanks, Anthony

@@optimascale6851 I'll try, thank you dude

Puedes usar la configuración de CO2 para establecer la cantidad de decimales que desees.

Typically try to calibrate like in the video. If that doesn't help maybe problem with main PCB. You might need to check the wiring. Here is another video on the channel about this. th-cam.com/video/tVbT5GvMI-o/w-d-xo.htmlsi=m8ziorYWR2xXBqfO Thanks, Anthony

Glad it helped! -Anthony

No since there is 4 load cells. The indicators only have room for 1 connection. You can connect one load cells directly to indicator but that is all. Other option would be to buy OP903 which has 4 5 pin connectors and attach a 5 pin connector to each load cell and connect that to each port of 903. Thanks, Anthony

@@optimascale6851 hermano,con mucha sinceridad agradezco el tiempo que te has tomado para contestarme.Te comento rápido,que yo calibré esa báscula la cual se usa para pesar ganado y el punto está que una vez calibrada cuando se realiza prueba de peso con una res el peso se mantiene oscilante,no estable.podría ser falta de configuración en la sensibilidad?

Sorry for taking long time to respond. Email sales@optimascale.com to place your order. Anthony

have you checked your port?

If your readout is older than 2-3 years old there might be a problem with the readout. You might need to replace. We discontinued the OP902 and replaced with OP909JR. Ask for the 4 to 5 pin adapter. email: sales@optimascale.com to place order. Otherwise it could be damaged cable someone is sales can help you with that. Anthony

@@optimascale6851 I'm sorry, I meant the three-position operational handle lever

Email sales@optimascale.com to purchase.

Only way to check is add voltage over red and black and measure output resistance as weight is being added.

You can use what you want. We have used the digi xbee in the past.

Anthony

email sales@optimascale.com with which color battery you have we have in stock.

You can use a 12 port junction box. We only have 10 ports here. Second option is to use to SECTIONAL junction boxes for example 2 8 port junction boxes where 1 goes into into to the input of the other junction box. Diagram would be readout -> junction box 1 (4 load cells) -> junction box 2 (8 load cells).

error 3 is input signal is negative. This usually happens when the green and white wires are swap and giving a negative signal. You can check the C15 setting to see how it responds to weight. The video on the channel called how to fix a floor scale explains more about this. error 4 happens when weight is unstable. Usually customers put too many decimals that their scale can't handle. Try to use less decimals and try out. If it still happens then probably damaged cable to readout. Check C15 setting as well. I haven't seen the dashes probably overload or short in cable. Try to go into settings and recalibrate. email: support@optimascale.com for any specific questions you have.

It should turn on when pressing the power button up front. Make sure power cables connected. Anthony

You would need some kind of software. Here is a video below on an example software we make. th-cam.com/video/MjL-30WFqMM/w-d-xo.html

Yes, we ship for ULINE as well. Sometimes they rebadge our scales as their own or find another supplier and do the same. All scales work the same so the any videos on this channel will help. Anthony

We sell this software. You can email: sales@optimascale.com to purchase. Mentions you want to buy data logging software. They can give you a price.

@@optimascale6851 thank you .

These are reachable. Same as a phone they are not meant to be replaced. These batteries should last from 3-5 years depending on how often they are used. Anthony

Calibration is stored on the indicator. Load cell is just a sensor. If you take the calibrated indicator and switch load cells to a different load cell of same capacity it will weigh the same.

I turn on my scale and all is says is "un-st then after a moment fluctuates in weight to 14kg and then goes to o-ld " it doesn't start up normally it just says unst ...

You can watch my video on how to fix a floor scale for a more detailed answered. th-cam.com/video/wcZWCF0RN1U/w-d-xo.html It could be wire in the wrong location, maybe needs to be recalibrated or bad load cell. Only way to tell is making sure all wiring is correct and tight and recalibrate. If there is water in the junction box then that will cause fluctuating weight. You will need to replace that junction box. You can email sales@optimascale.com for junction box replacement or if you find a bad load cell. Thanks, Anthony

Yes it is difficult. If you have a problem with one port you can check the F4 raw data for that connector and see what is going on. You can email: support@optimascale.com with your problem for more help.

T scale err4

Happens when weight is not stable. Make sure your test weight isn't moving. If it is not moving then check the wiring in the junction box in the platform. It could be 1 wire loose. Watch my how to fix a floor scale video on more details. Thanks, Anthony

@@optimascale6851 thank you, for showing me how to overcome it

Check the green and white wires and check that ohm reading. Then Green and black should be around the same. Load cells usually don't go bad. Try to rewire and check the C15 setting. Check out how to fix a floor scale video for more details. Thanks, Anthony
