Page 16: Operation Features
Normal Display Operation The TR150 has a full 7 digit display, which can be scaled using the calibration menu to suit the application it is to be used in. The display can display the instantaneous, peak or trough values. It is also possible to hold the display value (this only operates when not in peak or trough mode). -
Page 17: Hold Button
PEAK Button When pressed this button puts the TR150 into peak mode. This will display the highest display reading and hold it on the display until it is reset or a higher value is reached. To reset the peak display, press the peak and trough buttons simultaneously. -
Page 18: Configuration Menu Parameters
The benefit is that the battery life, based on a 350 sensor bridge being connected, increases from 45 hours to 450 hours. It is also important to remember that when the TR150 is re-calibrated with a sensor, the power save facility will be automatically turned off. The power save facility will therefore need to be re-activated after calibration has been completed. - Page 19 05 and 99 (00 de-activates activity for a continuous 25 minute period, then the TR150 will power down, to conserve power. If keyboard activity is detected at any time during the 25 minute period, then the time period is restarted.

If however, a higher sensitivity sensor is used with the TR150, it will be necessary to gain access to the internal PCB (you must turn the TR150 off) to move link LK1 to JP1 (see picture below) to allow the TR150 to accept sensitivities of up to 50mV/V. -
Page 21: Calibration Procedures
The best method of calibration, if it is possible to do so, is the calibration, as this reads in the sensor signal at two calibration points and scales the TR150 automatically. If this is not possible, then the sensitivity figure (in tAbLE mV/V) from the sensor calibration certificate can be used to scale the TR150, by using the calibration. - Page 22 You should now see displayed. This means the calibration was successful, press to the TR150 to normal operation mode, with the new calibration data stored. If you see FaiLEd, then you will need to repeat the calibration, checking that you have completed the procedure in the correct order, and that the sensor is connected correctly.

1. Ensure that the factory settings for gain and offset are set to 1 and 0, respectively. See millivolt per volt calibration section to do this. 2. Begin by connecting up the model TR150 and a high precision Multimeter to the calibration source set at 2.5mV/V with a 350 load. -
