Charge the battery
SE Lite is equipped with a Type-C charger which supports a maximum 45w PD quick charge. Fully charging the battery will take 4 hours typically. The battery indicator is red when charging, will turn green when fully charged.

Measure antenna height

To get the correct elevation value, we need to know the correct phase centre height of the receiver. However, it is almost possible to measure the phase centre directly. Normally, the software will read the receiver antenna offset parameters. Once user input the measurement height, the software will calculate the phase center height automatically. Typically, there are two ways to measure the height:

• Slant height (to measurement line)
  • Centring and levelling the tripod on a known point, then measure slant height from the ground point to the arrow at the side of the receiver.
• Pole height (straight height to device bottom)
  • Read the straight pole height

IMU Sensor
STEC SE Lite is integrated with a powerful calibration-free IMU sensor to give a better experience in real fieldwork.
IMU Tilt Survey
To initialize the IMU sensor, the receiver must be in a Fixed solution. In SurPad4.0 software, connect the device and click “Device” -> N“Device Settings”, to enable the “Pole Tilt Correction” function. Then, go to “Survey” -> “Point Survey” page. The software will guide a user to calibrate the sensor.

• Input the correct pole height.
• Draw a circle on the ground using the pole.
• Follow the guide and shake the pole back and forth for around 5-10 seconds or walk in a straight line around 10 meters until it shows “Ready”
