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 in which it is to be used. The display can show the instantaneous, peak or trough
values. It is also possible to hold the displayed value (this only operates when not in peak or
trough modes).
The display update rate, decimal point position and resolution can be set to suit.
The TR150 has two independent ranges. All values set in one range are totally independent
from the other.
Switching the TR150 On/Off
The TR150 is switched ON or OFF by pressing and holding down the button for 3 seconds.
It is also possible to set an Auto-off value in the configuration menu, so that the TR150
automatically switches itself off if there is no keyboard activity within a preset time.
RANGE Button
The range feature allows for one of two totally independent setup ranges to be selected. To
switch between ranges simply press the range button.
When you enter either the calibration menu or configuration menu, the parameters you will be
setting are those for the range you have selected. An annunciator is lit to identify which range
has been selected.
The TR150 is supplied with engineering unit legends; these can be slid into a window, located
on the inside of the front panel. These labels then help to further identify the units being
displayed for each range. Please refer to the photo below:-
