for calibration: Repeat calibration if the scale ever shows Out2. Incorrect calibration can occur if you do
not follow the steps exactly. If your scale does not perform accurately, please try replacing your batteries
before you calibrate. You will need a 100gram weight to calibrate this scale.
NOTE: if you do not have
access to a 100g weight you can purchase one at your local store or in emergency situations you can use
100g of coins or weights (ie 20 US Nickels = 100g) as a 100g weight
..
A) Instructions for the Z that does not have the switch on the bottom of the scale:
1)
Turn the scale OFF and Place the it on a Flat, very stable surface
(Be certain the scale is OFF)
2)
Press and hold the
key for 10 seconds until a random large
number appears on the display - then release the key.
3)
Press the
key again, the display will show 2Ero and then
100.0
4)
Gently place a 100 gram weight on the scale and wait 3 seconds.
5)
Press the
key. The display will show CAL and then PASS,
calibration is complete. Remove the weight, then Press and hold the
key for 5 seconds to turn the scale
off.
NOTE:
if after calibration your scale does not read accurately, this indicates calibration error and the
calibration process should be repeated more slowly.
Please calibrate on a very stable flat surface
B) Instructions for the Z with the switch on the bottom of the scale:
1)
Turn the scale OFF, Slide the switch on the bottom of the scale from "Norm" to "CAL". Then Place the
scale on a Flat, very stable surface (Be certain the scale is OFF)
2)
Press the
key, a random number will appear on the display
3)
Press the
key again, the display will show 2Ero and then 100.0
4)
Gently place a 100 gram weight on the scale and wait 3 seconds.
5)
Press the
key. The display will show CAL, PASS, then it will return to normal weighing and show
100.0.
6)
calibration is complete. Remove the weight, then slide the switch on the bottom of the scale from
"CAL" to "Norm".
INACCURACY / ERROR___________________________________
The primary reasons for inaccuracy or malfunction are low batteries, incorrect calibration, overload or
operating on an unstable surface. Please keep this in mind and maintain and operate your scale properly.
The scale is a precise instrument and must be handled with the upmost care and caution.
