Calibration Instructions
This scale has been calibrated at the
factory. However shock caused by ex-
treme changes in temperature, humid-
ity, and elevation can cause the scale
to lose calibration. To check the scales
accuracy, place a standard 350g cali-
bration weight on the scale. The scale
has an accuracy of +/- 0.1g, therefore
the display should read 350g (or at
least 349.9 or 350.1). If it does not,
recalibrate the scale as follows:
1. With the scale off,  rst press and
hold the “MODE” key. With the “MODE”
key still depressed, tap the “ON/OFF”
button. The display will show a model
number then “E-350”.
2. Place a 300g calibration weight (not
included) on the center of the platform
3. The display will show “300.0g” then
automatically turn off.
4. Calibration is complete! You may now
remove the calibration weight.
Note: If the standard calibration weight
is not used, the calibration may not  nish
automatically or the recalibration may not
be accurate.
Ask your scale supplier for calibration
weight availability.

Weighing
1. It is suggested that you warm the scale
up before use by turning it on for 20 sec-
onds and then turning it off again. Turn the
scale on once more to use.
2. After the display  ashes for 2 or 3

ready for use.
3. To change weighing units, press the
“MODE” key. The units will cycle through
as follows: g - oz - dwt - ozt (Gram -
Ounce - Pennyweight - Troy ounce)
4. Do not place objects exceeding the
capacity of the scale on the weighing
platform or the scale will read “H”. Dam-
age caused by overload is not covered by
the warranty.
5. Items being weighed should not be left
on the platform for longer than 5 seconds
or else the accuracy of the next item to
be weighed is affected.
Tare
Tare weighing allows you to subtract the
weight of a container to obtain the weight
of its contents only (net weight)
1. After turning on the scale and waiting
for the display to show “0.0”, place a tray
or container on the weighing platform.
Press the “TARE” button to return the
scale to zero. You can also achieve the
same results by placing a tray or con-
tainer on the platform with the scale off,
then turn the scale on. It will read zero
automatically.
2. If you then remove the container, the
display will show the containers weight as
a negative value. Press “TARE” again to
return the scale to zero.
