persons
WARNING: THIS APPLIANCE MUST BE EARTHED
IMPORTANT : The wires in this lea d are colou r ed in
Green/ Yellow: Earth
Blue: Neutral
Brown: Live(Phase)
As the colours of the wires in main leads may not correspond
with the colours marking identified in your plug/appliance,
proceed as follows:
The wire which is coloured Green & Yellow must be connected to
the Earth terminal marked with the letter E or by the earth symbol
accordance with the following code:

Black.
The wire which is coloured Brown must be connected to the
terminal marked with the letter L or P or coloured Brown or Red.
If in doubt, consult the instructions provided with the equipment
or contact the supplier.
This cable/appliance should be protected by a suitably rated and
approved HBC mains fuse : refer to the rating information on the
equipment and/or user instructions for details. As a guide, cable
of 0.75mm² should be protected by a 3A or 5A fuse. Larger
conductors would normally require 13A types, depending on the
connection method used.
Any moulded mains connector that requires removal
/replacement must be destroyed by removal of any fuse & fuse
carrier and disposed of immediately, as a plug with bared wires is
hazardous if a engaged in live socket. Any re-wiring must be
carried out in accordance with the information detailed on this
label.

2. INTRODUCTION
GPM-8212 Power Meter is a 16-bit CPU microprocessor equipped with
multifunction of full-digitized measurement, calibration and output. The
microprocessor has the advantage of high-speed sampling and calculation
function to accurately measure the distortion signal of waveform. Except for its
essential measurement on AC voltage, AC current, AC power, Power factor,
and Frequency, the power meter also provides additional features of PT/CT
ratio setting, display value holding, the value of maximum and minimum
holding, range selecting, aut o - ran ging and etc.
In order for an even more efficient and convenient communication, the
standard RS232 or RS485 is available as an option attached to the instrument.
The GPM-8212 is a low-cost, easy-to-use power measuring instrument.
