137.5M~2.7G Antenna Analysis Measuring Instrument Meter Vector Antenna Tester Standing Wave Meter Talent Tester

Features:

- The only UV band of all network talents, price, accuracy, and also the only UV band. With a minimum resolution of 0.001 impedance measurement, the joint can easily separate tension from elasticity

- The instrument has four interfaces: single point measurement, scan function, system information, calibration and calibration

Start the default access to the single point measurement interface.
 

Note:

For the convenience of the user, the calibration option is automatically changed to user calibration for each calibration. At the same time, to ensure the integrity of the calibration, the automatic power-off function will fail during the calibration process, ie the same startup will be maintained.
 

Boot and close:

Hold down the CTRL key while the power is off, and then press the switch key.

Start state, long press (2 S or more), change button, release, the instrument will turn off

Start state, long press (2 S or more), change button, release, the instrument will turn off
 

Some suggestions for using the instrument:

1. To ensure the accuracy of the measurement and calibration, preheat the instrument for at least 15 minutes.

2. Try to use the best quality RF cables and connectors.

3. The cable brand is well calibrated and will be used directly without calibration.

4, the measurement accuracy of the test cable will affect the process, so it is recommended, if possible, do not choose too long test cable.

5. When measuring and calibrating, please make sure there is no strong wireless signal around to avoid inaccurate measurement results.

6, if you do not understand the impedance measurement itself, you can consult the instructions and tutorials of the vector network analyzer. This instrument is equivalent to a single port vector network analysis function.

Charge:

Due to the high power consumption of the machine, the battery capacity is also larger. The designed charging current limit is Ma, and it can be charged for about 5 hours when fully discharged. If charging is active, 750 mA typically approximates current consumption, so in order to be able to charge normally, it will charge using a current output capacity that is 1 to 1 larger than the mobile phone charger. The battery of the instrument is not enough. Please charge it in time to avoid damage to the battery.

Storage and transportation:

Since the instrument contains the storage space of the lithium polymer battery, the device is turned off when fully charged. If the time is not long, it is recommended to charge once every 1 year to avoid damage to the battery.
 

Notice:

1. Reduce battery charging time and avoid long-term power-off state.

2. RF interface of SMA-K. Since the resistance of copper is lower than other metals, please be careful to protect it from falling and electric shock.

Warranty and Maintenance: This instrument provides a one-year free warranty after the device is sold.
