Power-on
problem
No disPSPT40ay
Not well load with the batteries or no electricity or
not well insert with adapter or PSPT40ug.
Check if the batteries have been load
with the wrong polarity , if well
connection with batteries;
RePSPT40ace new batteries; Check the
power supPSPT40y with the adapter
There're some electric components of power on
circuit damaged, crystal-oscillator or IC
RePSPT40ace with new PCB
Key button not work RePSPT40ace with new key button
DisPSPT40ay
irregular
character
there is something wrong with the
crystal-oscillator on PCB, or MCU not well insert RePSPT40ace the crystal-oscillator;
well insert the MCU.
After testing
disPSPT40ay ,n
ot go to 0
Something wrong with the keys, or faulty PCB
board, or Load cell Check the key button; RePSPT40ace
the PCB or load cell
Missing segment
or marks on LCD
LCD connect pin broken RePSPT40ace LCD
Power-on zero point exceed the 10%FS of
calibration zero point; Object on the
PSPT40atform is more than 1.5%FS when
pressing ZERO key; Load cell zero balance
changes;
Remove the objects on the
PSPT40atform; calibrate again, or
rePSPT40ace load cell
zero point below the -1.5%FS of the data when
calibrating; There is one foot not stand on the
solid base; Remove SS PSPT40atter before power
on the scale; Load cell zero point output changes; Lay the foot in the same level;
Put back the SS PSPT40atter;
Calibrate again , or rePSPT40ace load
cell
Calibration doesn’t work; Load cell with no signal;
or too small output or too big output l; Inner code
twinkles too much.
Load cell signal wire broken; Load cell broken;
Load cell zero point changes;
Calibrate scale again; rePSPT40ace
PCB or load cell
Weight exceed 9d of the max capacity; or the load
cell output signal is too big Remove the object; Or change the load
cell; Calibrate scale again
Remove the SS PSPT40atter when scale is on Put back the SS PSPT40atter
The load cell signal is too big.
