Basic Operations

It introduces basic process of starting working with the device.

Insert a SIM Card
The device supports network working mode.
To insert a SIM card, open the cover of nano SIM and insert a SIM card.

Charge the Battery
The device is equipped with Type-C charger which supports maximum 45W PD quick charge.
It takes 8 hours to fully charge the battery:

• Red indicator: the battery is in charging.
• Green indicator: the battery is fully charged.

To charge the battery, open the cover of type-C, and connect one end of the cable to the type-C interface and another end of the cable to the charger.

Connect to the External Power
Power supply from 5-pin port is supported, and the external battery within 9-28VDC is required.
CAUTION: It is not used for charging. Please use the original cable provided by us or cable with LPS standard.
To connect to the external power, open the cover of 5-pin port and connect one end of the cable to the 5-pin port and another end of the cable to the external battery.

Install the Radio Antenna
The antenna is required when the datalink is set to internal radio.
To insert radio antenna, open the cover of UHF radio, and install the radio antenna.

Measure Antenna Height
Antenna height refers to the vertical distance between the phase center and the ground. Since the antenna height cannot be directly measured, it is automatically calculated by SurPad software based on the measured height you input and measurement type you select.

CAUTION: No matter what the value of measured height you input and what kind of measurement type you select, the value of antenna height is unique.
The principle is as follows:

• h: the vertical height from the phase center to the ground.
• s: the slant height from the measuring line to the ground.
• a: the pole height, that is, the vertical height from the ground to the device bottom.

To measure antenna height, do one of the following:

• Set the measured height to the slant height and measurement type to slant height.
• Set the measured height to the pole height and measurement type to pole height.

The SurPad software automatically calculates the antenna height.

Start Tilt Measurement

The device can support both E-bubble and IMU, which is determined by the activation code and service you purchase, but you cannot use both of them at the same time.

Start E-bubble Tilt Measurement
It is required when tilt measurement is used and E-bubble is used.
Before starting E-bubble tilt measurement, to enable E-bubble tilt measurement, in SurPad software, press main menu Device → Device Setting, and set tilt survey to E-Bubble.

2. Optional: To modify antenna parameters, press Antenna Parameters, and set antenna parameters.
3. To start collecting tilt points, press Start.
4. Incline the pole with the inclined angle greater than 5°. The SurPad software automatically collects the first tilt point.
5. Change the inclined direction and repeat step 4 until 3 tilt points are collected. After 3 tilt points are collected, the following interface shows:
6. To save the result, press Save. The following interface shows:

Start IMU Tilt Measurement
It is required when tilt measurement is used and IMU is used.
Before starting IMU tilt measurement, to enable IMU tilt measurement, in SurPad software, press main menu Device → Device Setting, and set tilt survey to Pole Tilt Correction.
To start IMU tilt measurement in SurPad software, press main menu Survey → Point Survey to enter the main interface of point survey, and do as the prompt in the interface:
