MyWeigh DuraScale - Manual (Page 7)

6) When ‘xx pc’ is displayed (small pc in the upper part of the display, for example, ‘20 pc') is displayed,
the scale is in parts counting mode, You can place any quantity of an item on the tray and it will tell you
the total number of items. You can also perform the following operations:
<1>Press ‘PCS’ to exit parts counting state and go into normal weighing state;
<2> Press ‘TARE’ , to re-zero the scale
<3>Press ‘ON/OFF’, to turn off the scale
* ZERO (TARE)
Press Zero to reset the scale to zero. This can be used for eliminating from a sample (or a
Tray/Container) the weight value of a container weight is permanently removed for the remainder of
the procedure. Just turn the scale ON, place the tray or container on weighing platform, and press the
ZERO key. The scale will show 0.00 (or 0.0) on the display and you can add items to the container/tray.
NOTE: When all weight are removed from the weighing tray, the tared value of a container will be
displayed as a negative number. Cycle the power on the scale or press the TARE key to reset the scale to
zero.
** These electronic scale are precision instruments. Avoid disturbing environmental conditions such as
currents, vibrations, strong electrical and magnetic fields as well as a rapid change of the ambient
temperature.
A.ch.Er User Repair:
If your display is stuck showing A.ch.Er, it means that the signal coming from the load cell to the
processor is out of the range of normal. The most often cause of this is that the load cell has been
pushed down due to accidental overload (often when people are changing the batteries they
accidentally push down on the tray). Most of the time this can be fixed by simply pulling or prying up on
the tray (to bend the load cell slightly up so that it will be within spec). We build a lot of overload
protection into our design, but especially with a precise 0.01gram scale, it's still possible to accidentally
overload the scale.
Here is a typical email from a Durascale owner that fixed the problem using the above instructions: "OK I
pulled up on each side of the platform very gently. It flexed just a fraction of an inch, but it didn't seem
to be stuck down. I turned it on and it still had the dashes so I turned it off and did the calibration
procedure. To my surprise, it came up with the F50.00 and cleared to zero. I weighed a few things of
known weight and it seems to be working now. Thanks."
