    230 or 115 volts AC to 13.8 volts DC at 600mA. (NOT suitable if a 12V printer is connected.) . Plug Use only the power cable supplied by TRU-TEST it in to the socket marked 12V DC. on the Indicator and tighten the retaining collar by hand only. Calibration The Indicator automatically identifies and calibrates itself to the Loadbars connected.

  • Page 14: Operation

    Operation Operation Operation Operating the Model 702 is straightforward and TRU-TEST logical. Many functions are performed with a single key press. Safety To avoid damage, never load the scale further if the overload message appears on the display. Keypad The Indicator comes ready to use with default options set by the factory.

  • Page 22: Zeroing

    Zeroing Zeroing Zeroing To compensate for any build up of dirt on the weighing platform, the Model 702 has three methods of TRU-TEST zeroing the scale: • Power Up Zero • Automatic Zero • Manual Zero Power Up Zero The scale normally zeroes itself on power up, i.e. when it is turned On.

  • Page 23: Automatic Zero

    Automatic Zeroing (6 divisions maximum). See Model 702 Specifications on page 86. In some situations this feature should be turned Off. For example, when weighing animals in certain crates where opening and closing the doors may cause the Indicator to zero incorrectly.

  • Page 24: Manual Zero

    Zeroing Manual Zero If Automatic Zeroing is Off, the scale should be manually zeroed occasionally. To manually zero the scale: Remove load. Press Waiting for a stable zero reading: The Zero pointer comes On when the scale has settled. Zeroing differs from taring in that the capacity of the scale is not affected;...

  • Page 25: Taring

    Up to 100% of the live capacity can be tared. Very small weights cannot be Tared because, if the Tared weight is close to zero, the Model 702 assumes you TRU-TEST are clearing the Tare. When a Tared container is removed...

  • Page 26: Example Use Of Tare And Zero

    Taring Press Note: clearing the Tare does not zero the scale. Weights And Measures Versions • The Tare may operate down to 1 division. • The Tare feature may be disabled. • The ZERO key may be set to clear the Tare. (See Weights And Measures Versions on page 85).

  • Page 27: Fleece (Fine Weight) Mode

    Weight changes as small as 0.05kg (0.1lb) can be measured using a single Loadbar system (see the Loadbars TRU-TEST Manual). To view or change Fleece Mode setting see Setup Mode on page (Fleece Mode is disabled for particular markets and models, and when using Span Calibrated Loadbars.)
