Warning
Thank you for purchasing our ETCR4000A、ETCR4200A Intelligent Double
Clamp Digital Phase Volt-Ampere Meter (Full-automatic Double Clamp Digital
Phase Volt-Ampere Meter), in order to better use of this product, be sure to:
---- To read this user manual carefully.
---- Comply strictly with safety rules and precautions set out in this
manual.
Pay special attention to safety under any circumstances while using the
instrument.
Take note of the label text and symbols on the panel and back of the
instrument.
Make sure that the instrument and accessories are intact and there’s no
damage to the instrument or test wire insulation layer, or bare and broken
wires before using it.
Make sure that the function switch has been set up within the appropriate
range before the test.
Can not be used to test voltage higher than 600V.
It’s prohibited to use the instrument without the rear cover and battery
cover
in place.
Make sure that the connection plug is closely inserted in the socket.
Don’t use or replace batteries if the instrument is wet.
Test is prohibited in flammable and dangerous places.
The test line could only be pulled out from the instrument after being
removed
from the measured wire; don’t touch the plug jack by hand to avoid an
electric shock.
Do not use the instrument in strong electromagnetic environment in order
to prevent the equipment from work improperly.
Don't operating simultaneously two or more buttons, the operation will be
invalid.
Stop using the meter in case of metal exposure due to a broken chassis or
fractured test line.
-2-
Do not place or keep the device in hot and humid environment, or places
of
dew condensation or long time direct sunshine.
The instrument and current clamp must be maintained regularly to keep
clean, corrosive solution and coarse materials can't be used to clean the
clamp.
Keep the current clamp from any impact, especially the clamp joints.
The instrument has an automatic shutdown function.
Remove or replace the battery if the instrument is not used for a long time,
and take note of the battery polarity.
Take note of the measurement range and application environment required
for the instrument.
The operation, demolition, calibration and maintenance of the instrument
must be carried out by qualified personnel authorized to do so.
The meter should be stopped from being used immediately and sealed if
danger is brought up in case of continued use; only a competent body can
be authorized to deal with it.
The two COM ports of the instrument is internally short circuited, belong to
the same point.

Ⅰ． Introduction
ETCR4000A 、 ETCR4200A Intelligent Double Clamp Digital Phase
Volt-Ampere Meter (Full-automatic Double Clamp Digital Phase Volt-Ampere
Meter) is a well-developed full-automatic, multi-functional, digital, intelligent
meter specifically designed for field testing, which is a overall upgrade product
based on mechanical knob phase volt-ampere meter, can simplify operation
and reduce the possibility of misoperation, featuring high accuracy, high
stability, low power consumption, easiness to use and so on. It can directly
measure AC voltage and AC current without opening the measured circuit,
phases between three voltages, three currents and phase between the
voltage and current; in addition, the power factor and power of the circuit can
be indirectly measured, it can also be used to distinguish three-phase
sequence, transformer wiring group, inductive and capacitive circuits, test
second circuit and bus differential protection systems, read the phase
relationship between CTs of the differential protection, check the meter wiring
right, repair lines and equipment, etc.
ETCR4000A 、 ETCR4200A Intelligent Double Clamp Digital Phase
Volt-Ampere Meter has well designed shell mould made of newest material,
attach with shakeproof, skidproof, high insulation sheath, has a 240dots×
160dots LCD screen, all the test data display on the screen simultaneously,
vector diagram indication, and looks exquisite and comfortable. Meter
equipped with USB-RS232 interface, can store 500 sets of data, through the
system software upload stored data to the computer, implementing online
real-time monitoring and historical inquires, dynamic display. Can read, save,
report, print history data, etc. At the same time, its current clamps have two
kinds of specification optional, small mouth clamps are suitable for line
densely places, big round clamps are applicable to thick wire detection, to
meet the different place needs.

Volt-Ampere Meter (Full-automatic Double Clamp Digital Phase Volt-Ampere
Meter) applies to electric power, petroleum chemical industry, metallurgy,
railway, and meteorology, industrial and mining enterprises, scientific research
institutions, measurement sector and so on. Especially for the electricity billing
system and relay protection system, and electricity measurement, electricity
check, power inspection for power marketing department. Assembling, relay
protection, differential detection, start experiment, substation overhaul, or
power practical training, skills match for biotech department.
