The common breakdown of balance of MP series electron and means of settlement
From;    Author:Stand originally

1. Breakdown phenomenon: Balance switchs on the mobile phone self check cannot be passed, give now to list breakdown code
"EC1 " : CPU attaint
"EC2 " : Clavier mistake
"EC3 " : Balance stores data is lost
"EC4 " : Sampling module was not started

Reason: Fatal error causes balance to cannot work normally

Means of settlement: Send Hengping to repair balance please

2. Breakdown phenomenon: Balance shows " L "

Reason:

1) did not put scale
2) there is a foreign body below scale
3) air current cover and scale are touched together

Means of settlement:

1) find a place for scale in scale on
2) take scale examination to whether the eyewinker is below scale gently, take away an eyewinker
3) turn the cover examines scale or air current to whether have the appearance that touch gently, adjust the position that air current overspreads

3. Breakdown phenomenon: To load balance shows " H "

Reason:

1) object of the to load on scale is overweight, exceed maximum Cheng
2) ever used the weight used on a balance that is less than value of calibration weight used on a balance or other object calibration to cross balance, bring about put the weight inside normal span to show overweight.

Means of settlement:

1) it is only inside span limits metage
2) undertake calibration afresh with proper weight used on a balance.

4. Breakdown phenomenon: Switch on the mobile phone show " H " or " L " , to load shows invariant

Reason: Sensor attaint

Means of settlement: Send Heng Ping to change please sensor.


5. Breakdown phenomenon: Balance shows " E1 " , show spill over, indication value already exceeded 99999999

Reason: When reckon by the piece or percent say to weigh, sample value is too little

Means of settlement:

1) appear when reckon by the piece " E1 " , take away the object on scale above all, select a number of sample afresh, optional of 10 sample 2 times more integral, 5 times, 10 times wait as sample. Write down the multiple of next current sample, read when reading take indication value to multiply with multiple can. Detailed of particular operation measure sees " operation instruction handbook of balance of FA electron analysis " the 3.3.2nd reckon by the piece says to weigh.

2) when percent says to weigh, appear " E1 " , take away the object on scale above all, choose sample afresh. Detailed of particular operation measure sees " operation instruction handbook of balance of FA electron analysis " the 3.3.3rd percent says to weigh.

6. Breakdown phenomenon: Indication data once was followed say to weigh change and change normally, appear suddenly to change no longer

Reason: Once used the object that is more than value of corrective weight used on a balance to be used at balance calibration, appear thereby after be more than certain to indicate a value, show increase no longer
