Technical Details:
The microprocessor corrects the Non-Linearity of the Rectifier Diodes in the SWR sensor.
This ensures a high level of accuracy is achieved (typically 3%) over the range from 1 to
1000 watts.
The resolution for low power is 10mW. This is reduced at higher outputs due to the
number of digits available on the display.
A "fast" display and a slower Peak Value display (PEP) are provided.
The latter shows the maximum value that occurs within an observation period of 1
second.
A sample rate of 20 kHz is used (20,000 measurements per second). This
ensures that even short peaks are recorded and makes it suitable for Peak Performance
readings on SSB and CW modes.
Date and time:
The date and time feature is only included if requested.
It requires a different display, which unfortunately is
a bit more expensive.
Since it is displayed on a separate page, it makes the
Meter suitable as a station clock when not used for SWR.
The clock continues to run when the Meter is switched off thanks to its back-up battery.
The date and time can be manually set on another page. The accuracy is 1-2 seconds per
week.
The clock is set on a separate page that can be accessed by tapping on "adj. clock"
There, all numbers can be changed with the "+" and "-" buttons.
A good technique is to set the time approx. 10 to 20 seconds ahead of the actual time,
then while watching a reference clock, press the "set clock" button when this time is
reached. This allows you to set the device to the exact time.
The clock has an automatic feature:
The button on the bottom right of the page allows switching between "fix" and "auto"
modes. In "fix" mode, the time display always remains on. In "auto" mode, the device
switches automatically to the last selected screen as soon as RF power is applied.
Cleaning:
Do not use Tempo tissues or other paper towels to clean the screen surface; they cause
scratches. It is best to use alcohol and a microfiber cloth.
Microfiber cloths are available free of charge from opticians as a cleaning cloth for
glasses.
