1. Button description

Frequency tester

high frequency label tester

The buttons and interfaces of the whole machine are shown in the figure above. The interfaces include a microUSB charging port and an antenna magnetic connector.

There are four buttons in total, from top to bottom:

1) Power on/sleep button: Automatic sleep after 30 minutes of no operation, battery voltage lower than 3.6v, automatic sleep, 

3.7V alarm.

2) Menu selection key: cycle menu, automatically return to main menu "MANU" after 5 minutes without operation

3) Operation key 1: Correspond to the content displayed on the menu page

4) Operation key 2: Correspond to the content displayed on the menu page.

2. Functional area description

Function area description:

1: Battery voltage display: To ensure measurement accuracy, the battery voltage needs to be higher than 3.6v. (The analog part voltage is 3.3v,

LDO voltage drop is about 300mV);

2: Debugging information: return loss value

3: Resonance frequency-the frequency of the lowest point of the return loss curve.

4: Q value-the bandwidth ratio at which the transmission power at the center frequency is halved.

5: Return loss curve

6: Menu area.


3. Function menu description

1) Main page:

Normal/Expert display mode switch: Expert mode displays the curve, Normal mode only displays the value and the total measurement quantity.

2) Detection upper limit frequency setting: fMax+--upper limit frequency plus 1MHz; fMax---upper limit frequency minus 1MHz

3) Detection lower limit frequency setting: fMin+--lower limit frequency+1; fMin- --lower limit frequency minus 1

4) Backlight setting: bk+ backlight brightness plus; bk- backlight brightness minus

5) Calibration: O/S-short-circuit or open-circuit calibration, it is recommended to press this key to perform short-circuit calibration after connecting the coil;

Load-Load calibration, connect a 50 ohm load to the magnetic connector for calibration, if you pass the coaxial extension

For testing with a long wire connected to the coil, a 50 ohm load needs to be connected to the end of the extension wire for calibration.

6) Other settings: Restore Default-restore factory settings (calibrated data will not be overwritten)

5. use matters needing attention

1) A low voltage warning will be displayed when the battery voltage is lower than 3.6v;

2) The hardware of version 4.0 will completely cut off the battery power supply during sleep, so there is no need to worry about battery discharge if not used for a long time
