Still an important reference:
The ESM-2 electro-stress measuring device measures the body vol-
tages resulting from electrical alternating fields.
Except for this loading through electrical alternating fields, increased
values of magnetic alternating fields can also have an effect on the
body as stress e.g. through high-voltage lines, transformer stations,
roof current lines and different appliances, as well as through electri-
fied bus routes and, on a long-term basis, can also lead to serious
conditional disturbances and illnesses.
The Teslameter TriMag and DualField-2 has been developed for the
measurement of these magnetic alternating fields, about which ROM
Electronik GmbH would also be glad to inform you.
Maintenance of the device and battery change
For cleaning the device please use a slightly moistened cloth only.
Never treat the casing and the display with strong cleaning agents!
A necessary battery change is signaled through the symbols
"Doublepoint" in the display. Switch off the device then remove the
battery compartment cover on the reverse side, and take out the u-
sed battery. As a new battery, install a standard 9 volt battery (9 block
volt) and close the battery compartment with the cover. The device is
now ready for operation again.
