This is freq counter, it is useful for repair and measurement. it is as cheap as $3xx HKD in Sham Shui Po. I use it for radio phone measurement.

It is using 2 x 3A size battery, the package also be with rechargeable battery and charger. The measurement range is 1Mhz to 2.6Ghz

This model has one problem that is no LCD display. The conjunction is easy loose. There are no soldering connection and difficult to solder.

So, I use the white bubble plastic to press but non for long time. The plastic is loose after 1-2 days. 

At the end, I find a very elastic oil tube to press it under the PCB. It is normal at this moment, thanks my god. 

Using  2 screw to close PCB but oil tube.

 

Taking your own risk.¡@
