GINEERS G5102, Руководство пользователя

Страница: 20 / 27

Generally output characteristic of any load cell has non-linear parts in the
beginning and in the end. That is why it is good to use sensor with bigger capacity than
scale capacity. Optimal is to use a load cell with 2 to 3 times higher capacity. That way
its guaranteed that these non-linear stages will not be part of measurement range.
4.Menu „Other”
In menu „Other” are placed parameters which rarely should be set or changed,
even from service engineers. These parameters:
ƒ
Fact - set all parameters and calibrations to factory default values
Enter this menu by pressing button . Since here is only one parameter the only
buttons that work, are buttons and , respectively confirm or Exit.
4.1. Parameter „Fact”
With this option entire non-volatile memory of G5102 can be erased and all
parameters will be set to factory default values. It should not be used often – only when
the person setting the scale is in “dead end” and is wondering what to do with G5102.
Confirmation of erasing memory is on two levels - first button should be
pressed to enter in this function. Then user will see blinking sign “ Attent ”, which means
„Attention! You are going to delete all settings!”. If user presses again button , actual
erasing of whole non-volatile memory will begin. On display user will see sign „-hold-“ ,
which means that the user should wait process to finish and not turn off G5102 from
power grid until all is done.
Factory default settings for all important parameters are:
ƒ
Number of metrological divisions - n = 3000
ƒ
Weight division value - е = 1
ƒ
Decimal point position - dPP = 1
ƒ
Zero track speed - Ztrac = 0.5 e /1s
ƒ
Range of button - ZPerc = ±2% F.S
ƒ
Range of button - tPerc = 50% F.S
ƒ
Overload - oL = MAX + 8e
ƒ
ADC amplifying - А dc A = 1
ƒ
Sampling rate for 1 measurement - t-me = 150ms
ƒ
Bits for shifting right the result - Shr = 6 bit-a
ƒ
Zero position - 3000 divisions of ADC
ƒ
Full range swing in divisions - 20 000 divisions of ADC
ƒ
Fine correction - 0 е in Full scale
ƒ
Serial interface speed - baud = 9600bps, None
Scale serial number and firmware version of the scale, of course, are not deleted.
