Overview XT290

Digital Precision Level XT290 for setting-up and aligning most types of machine, for example levelling machine tables, rolls, bases etc. Other areas of use include straightness, flatness and parallelism.
The Precision Level XT290 can be wirelessly connected to your Easy-Laser® XT alignment app. Go to Measure with Display unit

NOTE! For correct values (positive and negative), always keep the yellow label in the same direction in the
different measurement positions.

 

Charge XT290

Charge XT290 by plugging in the power adapter. It is possible to keep on using the XT290 while it is charging,
see NOTE below.
Charging temperature: 0 to +40 °C [32 to 104 °F] (temperature inside the unit).

 

NOTE! For best measurement accuracy it is recommended not to charge the XT290 when measuring,
due to the generated heat.

NOTE! If you need to change the XT290 battery, please contact your Easy-Laser Distrubutor.

XT290 settings

Press to access settings in the Main menu.

NOTE! For the most accurate measurement result, the XT290 must be level calibrated and temperature adapted for the environment it is supposed to operate in.

NOTE! All settings, except temperature and zero point set with the Zero button, are saved even when the XT290 is turned off.

NOTE! When XT290 is connected to the XT app, the settings for "Unit", "Resolution" and "Filter" can only
be made in the XT app. When connected to the XT app, these display menus are disabled in XT290 and
"Factory reset" is completely disabled.

NOTE! When settings are changed in the XT app during connection, the app settings apply to the XT290. When disconnected, the XT290 settings return to the settings made before the connection.

 

Display view

Press and select "Display view". Choose from "Precision level" view for precision level & low accuracy inclinometer (roll), "Inclinometer" view for low accuracy inclinometer (pitch & roll) and "Cross view" for low accuracy inclinometer (pitch & roll).

 

 

 

 

Level Calibration

The XT290 is factory calibrated. To calibrate on site:

  1. Place the XT290 on the object to be measured (on a cleaned surface!). Make a mark to ensure that you place the XT290 in the same position
  2. Press and select "Calibrate". Wait until the value has stabilized. Press for OK.
  3. Rotate the XT290 180°. Wait until the value has stabilized. Press for OK.
  4. Press . The XT290 is now calibrated. The calibration is saved even when the XT290 is turned off.
  5. Rotate the XT290 180°, back to the original position. Now you can start measuring.

 

Filter

Press and select "Filter". Choose from "Low", "Medium" or "High" filtering time of measurement value.

 

Resolution (number of decimals)

Press and select "Resolution". Choose from "Low", "Medium" or "High".

Unit (angular)

Press and select "Unit". Choose from the following angular units:
mm/m, mils/inch, inch/foot, degrees or arc sec. Use to toggle the menu.

Shake warning

Press and select "Warnings" > "Shake warning". Choose on or off in the checkbox. Shake warning automatically disappears when shaking stops. If vibrations are too strong so that the shake warning appears during measurement, it is recommended to increase the filter level setting.


Temperature warning

lf the temperature warning appears during measurement, clear it by pressing if you want to continue measuring.
See note below.

Press again and select "Warnings" > "Temp warning". Choose on or off in the checkbox.
For temperature information, see Main menu > System info > Temp

The temperature sensor is located inside the XT290, on the precision level PCB.


NOTE!
The temperature warning will appear if the internal temperature of the precision level changes too rapidly. This can reduce the quality of the measurement. Always let the precision level warm up before starting the measurement, and make sure ambient temperature is stable.

 

Factory reset

Press and select "Factory reset" to return to factory settings (as when the XT290 was delivered).

System info

Press and select "System info" for information about serial number, firmware version, BGM (wireless) version,
part no and internal temperature of the XT290.
