The power meter is worthless in ALL respects. The biggest problem lies in the frequency you are using.
the closer you are to the 10 meter or 11 meter band, the more accurate your watt meter is. . .the lower your frequency, the further off your power meter is.
On the 40 meter band, I have it on the 100 watt scale, running 1200 watts into it, and showing only 50 watts out. 80 meter band only shows about 20 watts out, and the 160 meter band I need to switch to the 10 watt scale to show any kind of power out.

Modulation meter. . .I do not know if I can trust it or not. . .

SWR meter. . .Seems to be fairly accurate on all the ham bands below 30 mhz.

Frequency counter seems to be accurate on all frequencies below 30 mhz.

All in all, the frequency counter is good and the SWR meter is good. This is half of what the meter is supposed to do. . .the other half is worthless in my books. . .with a possible exception on the Modulation meter. . . which I have no way to accurately test it.
