4.2. Operation Keys
KEY DESCRIPTION
<POWER>
The <POWER> key is used to turn the instrument on and off.
<ZERO>
The <ZERO> key is used to execute zero level adjustment.
Use the <ZERO> key once empty scale has drifted away from zero reading.
-7-

MAS 640 Instruction Manual Rev. 0A
<TARE>
The <TARE> key is used to display zero on the display when an empty container is
placed on the weighing platform.
Use the <TARE> key to cancel mass of an empty container
<FUNCTION>
The <FUNCTION> key is used to select one of the special function. Refer to the
Special Functions [ section 5.] for the details on the available functions.
<PIECES> The <PIECES> key activates counting pieces of similar weight like screws,
nails, etc.
A long press of the <PIECES> key is used to declare the number of sample pieces
used as a reference for counting. For more details on how to use this function refer to
the Special Functions [ section 5.].
<PRINT>
The <PRINT> key sends the current status to a connected printer allowing a printout
of the displayed stable readings, i.e. weight, total weight, number of pieces.
Please note, readings must be stable on the display before printing.
4.3. Note on Stability
The Unit has to wait for stable readings when the <ZERO>, <TARE> or <PRINT> key is pressed.
That way execution of associated operation may be delayed by a few seconds. Readings are stable when you
see the LED of stable reading symbol [section . ] highlited.
If readings are unstable for more than 10 seconds message error -E06- will be displayed and printing
operation will be canceled.

-E06- The readings are not stable. Retry an operation when the readings
become stable.
-E07- The initial load exceeds 10% of the
maximum range.
Remove any load from the platform before
turning on the instrument.
-E08- Counting pieces resolution error occurred. For the counting mode, mass of the single
piece should represent at least 1/ of the
instrument minimum displayed division. Use
heavier item for counting.
