    Foreword: the eclipse series of scales/indicators continues to evolve. Original units were partially assembled integral units of platform and indicator, and pillar if chosen. They were factory wired and calibrated. Intermediate units (aprox. 10/99) were the same platform, indicator, and pillar compl...

    A. The information in this manual applies to the hr5000 series indicator, including those with rs-232 output unless otherwise indicated. Caution: this product is shipped from the factory set for 110- 120 vac operation. For 220-240 vac operation, settings must be changed before powering up. See setup...

    The hr5000 series scales are designed for light capacity, high- speed weighing operations. The indicators have a bright, 6-digit vacuum florescent display with annunciators for center-of-zero, net weight, and weight units. The hr5000 series indicators have a sealed toggle switch for zero and autotar...

    A. Installation 1. Unpacking and assembly: the indicator can be mounted on a pillar on the platform, or mounted with a bracket on the wall. 2. Pillar mounting the indicator (on an eclipse base): a. Use the instructions in bulletin 50628 for mounting the indicator to an eclipse pillar and platform. 3...

    B. Keys: 1. Units - triple function key function 1: switches the displayed weight between avoirdupois and metric weighing units. Function 2: when the units key is pressed and held for about 3 seconds, the indicator enters the front panel programming mode. Function 3: when a value is shown on the dis...

  • Page 10

    C. Switches : side of the indicator: the auto tare and zero functions are controlled by a toggle switch on the side of the indicator. It is used to toggle through values when in the programming mode. D. Annunciators: • various display annunciators are used in the display to indicate a function or mo...

    E. Leds • under: a steady yellow "under" led indicates that the weight on the scale is within a certain distance of the accept range on the low side (under range). The under (yellow) led will flash when the weight on the scale is much less than the the "under" range (out-of-range-low). • accept: a s...

    B. Standard a/d calibration: prom # 11750 (40300-250) rev x , before october 1999 the a/d counts are the indicator internal counts to convert the weight on the platform to digital information in the display. The counts are set by manipulating the gain and offset switches to reach the desire range. T...

  • Page 19

    Example: liveload counts = 4290 x 100.00 25.00 -or- liveload counts = 4290 x 4 (or) 17160 cts. The change in count value for full capacity weight should be between 30,000 and 39,000. Choose the appropriate gain setting from the chart below by selecting from the gain ratio chart below, the gain ratio...

  • Page 20

    5. With the gain switches properly set use the offset compensation chart below to select the deadload compensation. This compensation must be set to produce the lowest a/d count value with no weight on the platform, but not less than 1,000. 6. Verify correct operating range: a. By adding the a/d cou...
