CAUTIONARY NOTES AND PRECAUTIONS
Always handle your scale with care. The correct location and proper environment makes an important
contribution to the accuracy of the weighing results of TORBAL precision scales.
The optimum location for your scale:
• Stable, vibration-free base as horizontal as possible
• Away from direct sunlight
• Not exposed to high temperature variations
• Away from direct drafts
• The best location is on a stable bench away from direct drafts,
doors, windows, radiators and air conditioner vents.
CAUTION:
• The scale is designed for indoor use only.
• Do not operate the scale in hazardous areas or under dangerous conditions.
• Do not use the scale in locations subject to high humidity or dust.
• Do not connect cables in ways other than those mentioned in this manual.
• Set the scale on a firm, stable, horizontal surface.
• Never stand on or lean on this product. Equipment may fall or collapse,
causing breakage and possible injury.
• Before moving the product, unplug it and unplug all cables connected to it.
• When storing, transporting or returning the scale for service, always use the
original packaging.
WARNING:
• Never attempt to repair, disassemble or modify the scale. Tampering with the
scale may result in injury and cause greater damage to the equipment.
• Be sure to use the specified power source.
• Do not allow foreign matter to fall onto the scale.
• If water or other liquid spills onto the scale, unplug the power cord
immediately and contact technical support.

1. Carefully remove the scale, pan, and all of its components out of the packaging. Place them on a stable
surface where the scale will not be affected by any mechanical vibrations or high air movements.
2. After removing the pan base and the pan from their packaging, carefully install the pan base (2) onto the
scale by seating it on the pan support located in the middle of the scale. Once the pan base has been
installed, carefully place the pan (1) on the base.
3. Once the pan has been installed, level the scale by adjusting the front feet (6) until the level indicator (7)
shows the “air bubble” is in the center position of the sight glass. The level indicator is located on the rear
left side of the scale.

4. After leveling the scale, plug the AC adaptor to the AC adaptor socket located in the rear of the scale.
5. When the AC adaptor is plugged into the wall outlet, the scale will automatically turn on, and go through its
initialization process. If the scale is equipped with automatic internal calibration it will calibrate itself. The
calibration process will initialize automatically whenever the scale is turned on. The scale will also calibrate
whenever the temperature changes by 1 degree Celsius and at two-hour intervals. Calibration will initialize
only if the scale has been stable and idle for 60 seconds, in order not to interrupt weighing operations. The
scale will display “WWAIT” when calibrating.
Note – Automatic Internal Calibration Models: When the AC adapter is plugged into the wall outlet for
the first time, the scale will automatically and frequently initialize temperature calibration as the internal
parts of the scale heat up. The scale will display “WWAIT” when calibrating. Once the internal
temperature stabilizes, the scale will calibrate whenever the temperature changes by 1 degree Celsius and
at two-hour intervals.
Note: The scale will always start up in the mode that was enabled when it was turned off.
6. To put the scale into standby mode, leave the AC adaptor plugged into both the scale and the wall outlet and
press the Power “OFF” button. The “OFF” indicator will light up in the upper left corner of the display
signaling the scale is in standby mode.
