    3 INSTALLATION UNPACKING This indicator must be connected to a load cell platform and calibrated as necessary to match the platform and user requirements. See Section 15 for set-up information. The users application and the technical specifications of the platform or load cell will determine the necessary configuration.

  • Page 10: Connection

    E302-M model must use the 6 wire connection and has certain limitations for wire size and length. Refer to the Approval Test Certificate for details.

  • Page 11: Keypad

    Figure 1A shows the connections to a 6 wire load cell. Figure 1B shows a preferred method to attach a 4 wire load cell, using a 6 conductor cable to go from the indicator to the platform or load cell where it connects to the 4 wires from the load cells.

    Low to OK to High. 6 CALIBRATION COUNTER FOR APPROVED INDICATORS With approved (E302-M Model) indicators we have the ability to control access to the calibration or metrology parameters using a passcode to limit access. The requirements for doing this stipulate the code should be apparent and recorded in a suitable location on the indicator.
  • Page 15 The Counters are incremented any time the calibration section or the Factory parameters section have been modified. At power on, the display will show the current software revision number followed by the message of the Calibration Count “[AL[nt” then a number i.e. “123”. The number from the counter memory.

  • Page 16: Battery

    7 BATTERY The indicators can be operated from the rechargeable battery, if desired. The battery life is determined by the number and impendence of the load cells connected. With a single load cell and backlight disabled the life is approximately 70 hours before needing to be recharged.

  • Page 17: Operation

    10 OPERATION 10.1 ZEROING You can press the [Zero] key at any time to set the zero point from which all other weighing and counting is measured. This will usually be necessary when the platform is empty. When the zero point is obtained the display will show the zero indicator.

    Press [Tare] or [Zero] to remove the tare value and display zero. The Net indicator will disappear. 10.2.2 PRESET TARE (NOT AVAILABLE ON E302-M APPROVED INDICATORS) When the indicator is at zero with no weight on the platform it is possible to enter a preset tare.

  • Page 19: Weighing

    10.3 WEIGHING 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 unit of weight currently in use. To change the weighing unit press the [Unit] key. The only alternative weighing unit is pounds.
  • Page 20 Either place 10 parts on the platform for determining the average piece weight or use a different number of parts. For example, place 20 parts on the platform, press [CE] to clear the last values and then enter the value 20 using the numeric keypad.

  • Page 23: Check-Weighing

    10.5 CHECK-WEIGHING Check-weighing is a procedure to display an indicator or sound an alarm when the weight on the platform meets or exceeds the values stored in the memory. The memory holds values for a high limit and a low limit. Either or both the limits can be set by the user.

  • Page 24: Setting Up While Weighing

    10.5.1 SETTING UP WHILE WEIGHING Press the [Low Limit] key. It will show the current low limit. The “LO” symbol will appear on the display. Press the [CE] key to clear the old value and then enter the new low limit using the numeric keys.

    NOTE: 1. If the recalled limit is for parts counting, the display will show the last sample value used, ready for a new sample to be counted. 2. If the recalled unit is a percent weighing limit, the display will show the last sample value used, ready for a new sample to be weighed.
  • Page 28 Press [Tare] again to enter percent weighing. The indicator will set the sample mass on the platform as 100% reference weight. NOTE: If there is no reference weight on the pan and percent weighing function is entered, pressing [Tare] again will return the indicator to normal weighing.
  • Page 29 If the indicator shows “x x . x x %”, which is the last weight used as a reference, press [CE] to clear and use the numeric keypad to enter a new value. Press [Tare] to accept the new reference weight. The weight entered must be greater than 50 scale divisions.

  • Page 30: Animal (Dynamic) Weighing

    10.8 ANIMAL (DYNAMIC) WEIGHING The indicator can be set to animal (dynamic) weighing for weighing any items that are unstable or may move. See Section 13.4. The indicator uses a special filter to minimise the effects of any movement on the platform.

  • Page 31: Animal Weighing Procedure

    10.8.1 ANIMAL WEIGHING PROCEDURE With the platform empty the display will show zero weight.. Place containers or blankets onto the platform and press the [Tare] key to zero the display.

  • Page 32: Accumulated Total

    10.9 ACCUMULATED TOTAL The indicator can be set to accumulate when a weight is added to the platform automatically or manually by pressing [Print]. See Section 13.2. NOTE: 1. The accumulation function is available only during weighing. It is disabled during parts counting or percent weighing.
  • Page 33 When the indicator is at zero place a second weight on the platform. When stable press [Print] to accumulate the weight. The display will show "ACC 2" for 2 seconds and then show the new total. Continue until all weights have been added. This can continue for up to 99 entries until the capacity of display is exceeded.
