Calibration Instructions

  This scale has been calibrated at 

the factory. However shock caused 

by extreme changes in temperature, 

humidity, and elevation can cause the 

scale to lose calibration. Always use the 

correct calibration weight for your scale:

ZX-60 : 50 Gram Calibration Weight

ZX-250: 200 Gram Calibration Weight 

ZX-600 : 500 Gram Calibration Weight

Calibration weight is not included

1. With the scale off, first press and 

hold the “MODE” key. With the “MODE” 

key still depressed, tap the “ON/OFF” 

button. The display will show a number. 

You may now release both keys.

2. Press the “ON/OFF” key again. The 

LCD will display ZERO then the required 

calibration weight value(ie 50g, 500g).

3. Place the required weight onto the 

platform and press “ON/OFF” again. The 

LCD will display “PASS”. Calibration is 

complete!

Note: If the standard calibration weight is 

not used, the calibration may not finish 

automatically or the recalibration may not 

be accurate. Check your scale supplier for 

calibration weight availability.
