Useful information
1.1 Measuring magnetic fields
A Gaussmeter is a measuring instrument used to measure
the strength or direction of magnetic fields. The unit of measure
for magnetic field strength is the tesla. As this is a very large
unit for most practical uses, scientists commonly use the
nanotesla (nT) as their working unit of measure. Engineers often
measure magnetic fields in Gauss (1 Gauss = 100,000 nT, 1 T =
10000 gauss).
1.2 About this instrument
G81 Gaussmeter adopts Bypass Zero Technology
(patented technology) and high-stability GaN hall sensor,
without zero calibration, which greatly improves the accuracy of
the data and the convenience of use. G81 also has extremely
low measurement noise that is unique in a handheld
gaussmeter. The peak-to-peak noise within 60 seconds is less
than 0.05G. It can easily measure the metal materials’
remanence and even measure the earth's magnetic field (about
0.4G).
The DC accuracy of Gaussmeter G81 is better than 0.8%,
the measurement range is up to 100kG (10T), and the frequency
response range is DC-10kHz. Gaussmeter G81 uses Fourier
analysis method to measure AC magnetic field (RMS value and
spectrum analysis), which is very suitable for measuring AC
magnetic field of various waveforms (sine wave, square wave,
triangle wave, trapezoidal wave, sawtooth wave, etc.).
The Gaussmeter G81 uses a 3.2-inch color industrial
resistive touch screen and a menu and display that conform to
the smart phone habit. It is easy to operate, and users can use
it without reading the manual. The Gaussmeter G81 is powerful,
with maximum/minimum functions and magnetic field polarity
display function, storage function, real-time spectrum analysis
function and 0.2ms pulse magnetic field capture function.

Safety instructions
2.1 Using this operating manual
! Carefully read this entire operating manual before you
start using the instrument.
! Keep this operating manual so that it is available to
everyone who uses the instrument, and ensure that this
operating manual is with the instrument if you pass it on to a
third party.
2.2 Proper use
The G81 gaussmeter is designed to measure and
evaluate magnetic fields.
! Only use the instrument for the purpose and under the
conditions for which it has been designed.
! In particular, observe the technical data given in the
“Specification”.
! Ensure that only qualified personnel with appropriate
training can use the instrument.
2.3 Improper use
The G81 gaussmeter is not a warning device that gives
active notice of the existence of dangerous fields by means of a
visible or audible warning signal.
! Remember that this instrument is a measuring device,
not a warning device.
2.4 Dangers when handling rechargeable Batteries
When handled improperly, rechargeable batteries can
overheat, explode, or ignite.
⇒Only use the G81 gaussmeter with its rechargeable
batteries.
Do not use dry batteries.
