About IT-E185
IT-E185 is an optional accessory for the User of ITECH, which is mainly for
convenient wiring during test with IT9121/IT9121E power meter. See the figure
below for IT-E185:
Dimension
IT-E185 dimension figure is as follows:

①Voltage input terminals
②AC power input socket
③Current input terminals
Connecting Fixture
During AC input power consumption test of AC-DC adapter, the IT-E185 is
required to connect IT9121/IT9121E to the adapter and grid lines in series.
When the measured current is relatively large, connect the voltage input
terminal to the side that is closest to the load. When the measured current is
relatively small, connect the current input terminal to the side that is closest to
the load. both circuit figures are as follows:

Measuring higher current:
Measuring lower current:
Voltage input terminal
The terminals are safety banana jacks (female). Only insert a safety
terminal whose conductive parts are not exposed into a voltage input
terminal.
Current input terminal
The terminals are binding posts, and the screws are M6. Either wind a
wire around a screw or pass a crimped terminal through the screw axis,
and then tighten firmly with the terminal knob.
Connecting Method
The connection method for measuring the low-current measurement circuit is
as follows:
1. Open the current terminal protection covers of the power meter and the
device.

2. Put the DUT input terminal to the three-core socket on the front panel.
3. Connect the voltage and current terminals of IT9121/IT9121E power meter
to the corresponding terminals on the rear panel, as shown below:
NOTE
Connect the voltage positive terminal of the power meter to the V+2 terminal on the rear
panel and put the V+1 suspended when high current is measured.
4. Connect theAC power input socket of the rear panel to the 220 VAC input,
as show above.
5. To guarantee personal safety, after the measurement circuit is connected,

please install the current terminal protection cover to avoid touching the
current terminal during measurement.
Application Case
When testing the AC input power consumption of AC-DC adapter,
IT9121/IT9121E is required to be connected to the adapter and grid lines in
series.
Without Fixture
When the device is not used, cut off the plug that connects to the grid lines and
lead out the internal L, N and GND wires. Connect the voltage and current
terminals of the power meter to the circuit following the principles of voltage
parallel circuit and current series circuit.
Use Fixture
When the fixture is used, the wiring is simple without damaging the original plug.
Wiring steps are as follows:
1. Put the DUT input terminal to the three-core socket on the front panel.

2. It is not necessary to cut off the plug. After the current passes through the
device, the device will automatically strip the voltage and current terminals
from the three-core plug. Connect the corresponding voltage and current
terminals to the terminals on IT9121/IT9121E power meter.
