The TR150 is a completely portable, precision instrument packaged in a small, robust IP65 (NEMA 4) enclosure, weighing only 260 grams. The TR150 accepts an input range of up to 50mV/V.

For simplified use, the operator only has access to six keys; on/off, gross/net, peak, trough, hold and shunt cal. Calibration and configuration can be performed from the front panel, with protection against accidental or un-intentional changes. The configuration menu is very simple and enables the setting of a tare value, display resolution, filter rate, auto power off and selection of low power mode.

There are 3 calibration options; a single pass auto-calibration, entering of load cell sensitivity and corresponding display value and entering of offset and gain values for corresponding display values.

Two separate ranges are available, which enable the instrument to read and display two separate parameters; i.e. lbs/kg, tonne/kN, high/low resolution, fast/slow response etc. The menu options offer the engineer the ability to tailor the instruments response to the application. In each range all the variables can be set, including zero and filtering.

Annunciators on the display give a constant indication of the operating mode of the TR150.

The TR150 features an innovative power saving facility which, when enabled can offer up to 450 hours of battery life with a 350 ohm bridge connected. In normal power mode up to 45 hours battery life is achieved with a 350 ohm bridge. The TR150 also incorporates an auto power off facility, which can be set during configuration in 1 minute increments up to 99 minutes, or it can be disabled so the instrument is powered on until the off key is depressed.

The TR150 is supplied with a leather carry case, which enables the full operation of the indicator whilst fitted in the case.

CALIBRATION

The TR150 Crane scale is calibrated once a year to ensure accuracy of the load. The following two options are available:

• The scale is calibrated using four test points, this is a less expensive method of calibration as the process is relatively fast and on completeion a certificate of test and examination is supplied.
   
• The scale is calibrated by C.S.I.R. with extensive testing done using numerous test points. The C.S.I.R. calibration is more costly due to the length of the process. This test and examination process is more thorough and extensive and a C.S.I.R. certificate is supplied on successful calibration
