Our pro scale is not working and showing “b fail”. What is the problem here?
Pedro,
When the Readout displays this message it means the battery voltage has dropped to a level where reliable operation is no longer possible. Install a new battery (CR123) or batteries (2 AA Alkaline) to clear this message.
Thanks for your prompt reply, Currently we had 3 brand new units of Pro Table with ProScale Digital Display, I have checked the battery voltage on the other unit by pressing the datum button, it read 2.76dc, i take out that battery and put it on the unit with “b_fail” display. but still the “b_fail” display is there. When I took the battery from the unit with “b_fail” unit, and put it on the other unit, it works fine..
And one more thing the display is not turning off even I press the on/off button. We are still sourcing the CR123A battery, thats why I tried checking the other battery on the units that are working fine.
Pedro,
When the battery level gets to 2.85 volts, the low battery indicator will show in the lower left corner of the LCD.
Note: The readout only checks the battery voltage once each 10 minutes, so you may not get the low battery indicator to show instantly when a battery is moved from one readout to another.
Also, when battery voltage is lower than 2.84 volts and a primary key is pressed, the readout will show b Fail message. This indicates that the battery voltage is too low to allow safe writing to memory.
In either case, a new battery should be installed.
We just noticed that the reading of our proscale is different to each other when we measure 1 same part. We have 3 proscale as I stated before, the one with b fail already have its new battery and the b fail error is gone. Now when we measure the same part on other pro scale there is difference by 0.2 mm to 0.3mm. How can we resolve this issue and what are the factors affecting this problem. thanks
Pedro,
The ProTables are designed to have an accuracy error of no more than .003 inches (.076mm). Measuring the same part of different tables may yield different results but all of the measurements should be within .08mm of each other. Be sure that the ProTables are being supported on a flat solid surface and that the leveling feet are adjusted properly so that the ProTable does not rock and is level. Be sure that the digital readout is displaying ABS in the upper left corner of the LCD readout, not INC.
Can we use a ProScale measurind system with Allen-Bradley PLC 500. If yes how, can we comunicate over DH+ .
Thanks
Steve,
The ProScale readouts typically require an interface device to allow them to communicate with external devices. In the case of a PLC, you can choose to use an Analog Interface Unit which provides 0-5/0-10 VDC analog output relative to an encoder position. You can also use a 3rd party RS-232 interface to provide a serial output in ASCII.
Thanks, can you give me some example of 3rd party RS-232 interface please ?
The unit that we recommend is from Microridge. You can see the product here: http://www.microridge.com/gageway_sm_series.htm
