- Page 3 INTRODUCTION The TCW series of scales provides an accurate, fast and versatile series of general purpose weighing scales with counting, % weighing and check-weighing functions. There are 2 series of scales within the range, TCW scales use kilograms as the default unit and the TCWa range are changeable from pounds to kilograms.

Page 7: General Installation
INSTALLATION GENERAL INSTALLATION The scales should be sited in a location that will not degrade the accuracy. Avoid extremes of temperature. Do not place in direct sunlight or near air conditioning vents. Avoid unsuitable tables. The tables or floor must be rigid and not vibrate. Do not place near vibrating machinery. -

KEY DESCRIPTIONS Zero or Set the zero point for all subsequent weighing. The display shows zero. A secondary function , or "Enter" key when setting parameters or other functions. Tare or Tares the scale. Stores the current weight in memory as a tare value, subtracts the tare value from the weight and shows the results. - Page 9 DISPLAYS The LCD display will show a value and a unit to the right of the digits.

Page 10: Operation
OPERATION ZEROING THE DISPLAY You can press the ZERO/ENTER key at any time to set the zero point from which all other weighing and counting is measured, within 4% of power up zero. This will usually only be necessary when the platform is empty. When the zero point is obtained the display will show the indicator for zero. -
Page 11: Weighing A Sample
WEIGHING A SAMPLE To determine the weight of a sample first tare an empty container if used, then place the sample in the container. The display will show the weight and the units of weight currently in use. PERCENT WEIGHING The scale will allow a sample weight to be shown as 100%. -
Page 12: Check-Weighing
CHECK-WEIGHING Check-weighing is a procedure to cause an alarm to sound when the weight on the scale meets or exceeds values stored in memory. The memory holds values for a high limit and a low limit. Either limit can be used or both can be used. Press the LIMIT key. -
Page 13: Accumulated Total
LIMIT/ key to recall the current settings. Pressing FUNC/C key when the current limits are shown to clear the settings, then pressing the ZERO/ENTER key to store the zero values. ACCUMULATED TOTAL The scale can be set to accumulate automatically when a weight is added to the scale or manually by pressing the PRINT key. - Page 14 While the weight is on the scale it is permissible to press the PRINT key to store the value immediately. In this case the scale will not store the value when the weight is removed. The totals can be viewed as above. In all cases the scale must return to zero or a negative number before another sample can be added to the memory.
- Page 15 PARAMETERS The scale has 6 parameters that can be set by the user. These allow the user to set the scale to: • Display the weight in other increments of weight to minimise the affects of vibration, wind or other environmental conditions. •...
- Page 16 The displayed unit of weight is set next. The scales are normally calibrated and display in kilograms, however they will show the weight in grams, ounces or pounds and selected by this function. Press the TARE/ key to change the value then press the ZERO/ENTER key. TCWa SCALES The TCWa scales have a key to change from kilograms to pounds immediately.

Page 17: Battery Operation
Continue to charge overnight for a complete recharge. As the battery is used it may fail to hold a full charge. If the battery life becomes unacceptable then contact Inscale. - Page 18 RS-232 OUTPUT The TCW Series of scales can be ordered with an optional RS-232 output.

Page 21: Error Codes
ERROR CODES During the initial power-on testing or during operation it is possible the scale may show an error message. The meaning of the error messages is described below. If an error message is shown repeat the procedure that caused the message, turning the balance on, calibration or other functions. - Page 22 Shielded interconnect cables must be employed with this equipment to insure compliance with the pertinent RF emission limits governing this device.
