DC Output
This output supplies a signal equalling minus 0.5 mV per digit. That
would, for example, translate into minus 1 Volt at a maximum reading
"2000 nT/Vm" or "200 nT/Vm". The negative signal was preferred
over the positive signal because it clearly offered better linearity and
correspondence with the display value.
The NFA line of instruments from Gigahertz Solutions offers a simpli-
fied three-dimensional frequency analysis and data logging of alter-
nating magnetic field (NFA 400/1000: also electrical fields).
Battery, Auto-Power-Off, Low batt.
The meter is powered by an internal 9 V NiMH battery. It will auto-
matically be shut off after approx. 40 minutes of continuous use in
order to save battery capacity. Once "Low. batt." appears in the cen-
tre of the display, the field meter will already turn off after 3 min. in
order to avoid measurement errors. Reliable measurements can no
longer be guaranteed.
For charging please connect the A/C adapter, and switch the meter
on and off once. The green LED will light up during the complete
charging process. The meter is fully charged after about 12 hours of
charging, or once the green LED turns off.
Possibilities of Remediation
If possible, increase the distance to the source of pollution
Correct "Plugging":
Switch the meter to "E" and place it between e.g. the bedside light
and the pillow. Switch off light. Reverse direction of plug by 180° and
re-insert it. Logical consequence: leave plug in the direction of lowest
readings. This trick works best for an inline cable-switch of e.g. the
lamp.
Use shielded socket-lines with two pole switch (please see website)
and shielded connection cables.
Install an automated "demand switch" in the house fuse box which
cuts electricity as soon as the last load is switched off, and automat-
ically reconnects as soon as electricity is needed again. As long as
everything is switched off, there is no tension on the line and hence
no pollution in the room. This is the most comfortable and effective
measure you can take. Check www.gigahertz-solutions.com for most
sophisticated and well reputed models.
It's easy to check for yourself whether a demand switch is a good
investment for you (easiest in pairs):
 One person reads the meter on the bed to be inspected. Switch
the meter to "E".
 The other person switches off the relevant fuses (one by one and
different combinations)
 Install the demand switch into those circuits which show the high-
est reduction of field strength.

fessional "building biologists" can be found on our website.
