4.0 GETTING STARTED
4.1 Connecting The Probe
Grasp the connector located at the end of the probe cable and carefully
insert the connector plugs into the receptacle located at the top edge of the
gauge. Make sure the connector is fully inserted into the receptacle. The
orientation of the plugs does not matter as they are non-polarized.
4.2 Turn On The Power
Press the key. All of the LCD Display elements will momentarily
illuminate. The firmware revision will then be momentarily shown
(for factory troubleshooting purposes only). Eventually the display will
show “0.000” (or “0.00” if using metric units), indicating it is ready for
use.
Note: 1. The gauge is turned off by pressing the key again.
2. The gauge will automatically power off after 5 minutes of
non-use.
3. All settings will be retained in non-volatile memory.
4.3 “Zeroing”The Probe
The Probe Zero Plate is used to “zero” the probe for calibration purposes.
Normally, this procedure is required only when the probe is connected to
the instrument for the first time, but since this process takes less than 10
seconds, we recommend performing the Probe Zero function occasionally
as described below.
1. Check that the probe face (wear surface) is clean and free of debris.
2. Place a small drop of the supplied coupling fluid on the built-in
Probe Zero Plate located on the top of the gauge.
3. Press the probe firmly against the Plate.
4. The Stability Indicator on the LCD display should have six or
seven bars illuminated and a value should be shown in the display.
5. While maintaining probe contact with the Test Plate, press the
key. The display will show “Prb0” while the TI-25M
calculates its zero point.
Note: The value shown on the display can be recorded and used in the
future to confirm that the gauge is functioning properly.
