Example 1: TONSExample 1: TONSExample 1: TONSExample 1: TONSExample 1: TONS

Assume you wish to display weight inTons and the I150 is calibrated in pounds.

One ton = 2000 lbs, therefore the conver-sion factor is 2000.

To enter the conversion factor, it mustfirst be converted to scientific notation:

“.2” is the mantissa (between 0.1 and 1),and “4” is the exponent (power of 10)

Using this conversion factor, the I150 willdisplay 1 custom unit for every 2000 lbson the load receiver.

When weighing material or objects thatmust be held in a container, taring en-ables the indicator to save the containerweight in memory, separate from theweight of the material in the container.The I150 permits you to set tare values intwo ways as explained in the followingexamples.

Example 1: Unknown Tare WeightExample 1: Unknown Tare WeightExample 1: Unknown Tare WeightExample 1: Unknown Tare WeightExample 1: Unknown Tare Weight

1. Place an empty container on the loadreceiver, and read its weight on thedisplay. Notice that the GROSS indi-cator is ON.

2. Press TARE.

StabilityIndicator

Example

When the display becomes stable, itwill show zero and the NET indicatorwill be ON. The container’s weight isstored in memory.

3. Add the material to be weighed to thecontainer. As material is added itsnet weight will be displayed.

4. To view the combined weight of the

material and the container (gross

weight), press GROSS.

Repeatedly pressing GROSS will

cause the display to switch between

the gross weight (container and ma-

terial) and the net weight (material

only).

NOTE: The combined weight of the con-tainer and material must not exceed thecapacity of the load receiver.

Err 0: Invalid memory checksum. Checksum is verified every time I150 is turnedon. Check setup parameters in menus and recalibrate. If error persists, ahardware problem may exist and unit must be serviced.

Err 1: Overload condition. Load exceeds 103% of rated capacity.

Err 2: A/D output out of linear range. Zero adjustment may be needed. If the errorpersists after zero adjustment, unit must be serviced.

Err 4: Calibration error. Requested resolution exceeds internal A/D resolution.Repeat calibration or linearization procedure. Make sure correct calibra-tion weights are used.

Err 5: Value is too large to display; exceeds 999999 counts. Caused by an invalidCustom Unit Conversion Factor.

Err 7: All weighing units have been disabled (set to OFF) in the “SELECT”parameter of the scale submenu. At least one weighing unit must be on.

Err 8: Maximum allowable graduation exceeded. Max available graduation is500000; min available graduation is 0.00001.

Err 10: Non-volatile memory write error. Indicates hardware error. Retry lastoperation performed. If error persists, unit must be serviced.

Err 11: Unable to obtain stable data. Occurs when stable data is required (i.e.during calibration, or taring in legal for trade installations). Check thatplatform is not subject to drafts, vibration, etc..

Err 12: No numeric entry is expected. Menu parameter requires you to make aselection; will not allow a numeric entry.

Err 13: An attempt was made to enter too many digits.

Err 14: The maximum load that may be zeroed by pressing the ON/ZERO buttonhas been exceeded. See “ZERO” parameter in setup submenu.

Err 15: Tare data not valid; capacity exceeded. Tare values may be entered onlyup to the capacity of the platform. Negative numbers not accepted.

Err 16: Average piece weight value entered is too small to accurately count parts.

Err 17: ID number store/recall error. An attempt was made to store or retrieve aninvalid ID code (i.e. too many digits, decimal point included, etc.)

Err 18: In-Out data not valid.

Err 19: Sense channel not operational. If sense is not used, “SENSE” parameterof setup submenu must be set to OFF.

Err 20: Calibration is required after certain menu parameters have been changed.Changes are not saved when this error occurs. Return to menus, setparameters, and recalibrate before exiting menus.
