The top button will decrement the frequency; the bottom button will increment it.
The center button enters the menu, where the setup of the power meter
may be adjusted:
Contrast
: LCD contrast, not normally necessary to change this, but it the display is difficult to read, it
may help to adjust this.
Mode
:
Peak
or
Avg,
use Avg mode for a more precise reading of continuous RF sources, such as A/V
transmitters. Use
Peak
for pulsed sources, such as UHF uplinks, or wireless networking equipment.
Mode:
dBm
or
mW
. Measurement readout format.
Attenuation
: Enter the attenuation, in dB, of any attached attenuator(s). For multiple stages of
attenuation, enter the total attenuation (e.g. 10dB + 10dB = 20dB of attenuation).
If calibration data for the attenuator is available, use the
Fine Attenuation
control also.
NOTE: If the Pwr value is flashing, the measured power is outside of the power meter’s range, either too
low, or too high. The former is just a warning that the displayed value is not accurate (and will occur
when power is applied with no RF connection), the latter is a warning that the meter may be damaged.
Firmware Upgrade
If for any reason a firmware upgrade is needed, be sure to use a version of the ImmersionRC Tools later
than March 2010 to upgrade.
Using the correct version of this tool will ensure that the calibration curves, measured during testing, are
preserved, and therefore the accuracy of the device is preserved also.
It is highly recommended not to upgrade firmware in the power meter unless instructed to by
ImmersionRC.
