•Do not use the instrument if it is damaged. Before operation, check
the casing to see whether it cracks. Do not operate the instrument
in the presence of inflammable gasses, vapors or dusts.
•The instrument is provided with a power cord during delivery and
should be connected to a socket with a protective earth terminal, a
junction box or a three-phase distribution box. Before operation, be
sure that the instrument is well grounded.
•Please always use the provided cable to connect the instrument.
•Check all marks on the instrument before connecting the instru-
ment to power supply.
•Ensure the voltage fluctuation of mains supply is less than 10% of
the working voltage range in order to reduce risks of fire and elec-
tric shock.
•Do not install alternative parts on the instrument or perform any un-
authorized modification.
•Do not use the instrument if the detachable cover is removed or
loosen.
•To prevent the possibility of accidental injuries, be sure to use the
power adapter supplied by the manufacturer only.
•We do not accept responsibility for any direct or indirect financial
damage or loss of profit that might occur when using the
instrument.
•This instrument is used for industrial purposes, do not apply this
product to IT power supply system.
•Never use the instrument with a life-support system or any other
equipment subject to safety requirements.

•SHOCK HAZARD Ground the Instrument. This product is provided
with a protective earth terminal. To minimize shock hazard, the in-
strument must be connected to the AC mains through a grounded
power cable, with the ground wire firmly connected to an electrical
ground (safety ground) at the power outlet or distribution box. Any
interruption of the protective (grounding) conductor or disconnec-
tion of the protective earth terminal will cause a potential shock
hazard that could result in injury or death.
•Before applying power, verify that all safety precautions are taken.
All connections must be made with the instrument turned off, and
must be performed by qualified personnel who are aware of the
hazards involved. Improper actions can cause fatal injury as well as
equipment damage.
•SHOCK HAZARD, LETHAL VOLTAGES This product can output the
dangerous voltage that can cause personal injury, and the operator
must always be protected from electric shock. Ensure that the out-
put electrodes are either insulated or covered using the safety cov-
ers provided, so that no accidental contact with lethal voltages can
occur.
•Never touch cables or connections immediately after turning off the
instrument. Verify that there is no dangerous voltage on the electro-
des or sense terminals before touching them.
•After using the device, turn off the power switch of the device be-
fore unplugging the power cord or disassembling the terminals. Do
not touch the cable or the terminal immediately. Depending on the
model, the dangerous voltage at the plug or terminal is maintained
for 10 seconds after the device is switched off. Make sure that there
is no dangerous voltage before touching them.
•Failure to use the instrument as directed by the manufacturer may
render its protective features void.
•Always clean the casing with a dry cloth. Do not clean the internals.
•Make sure the vent hole is always unblocked.

Function Introduction
For an introduction to the interface, see 1.3 Home-Screen Overview.
The IT2800 supports the following measurement parameters. The
measurement parameters displayed in the actual interface are associated with
the settings of Menu→Config→Measure→View Type.
Copyright © Itech Electronic Co., Ltd. 9

Quick Reference
•Current
•Voltage
•Resistance
•Power
Resistance data is given by Resistance = Vmeas/Imeas.
Power data is given by Power = Vmeas * Imeas.
In the above formula, Vmeas is the voltage measurement data, and Imeas is
the current measurement data.
Parameter Setting
The Meter interface also supports the setting of voltage and current values, as
well as the selection of voltage and current ranges.
Voltage value setting:
Based on the Menu→Config→Source Mode setting is Volts (Voltage source
mode) or Amps (Current source mode), the Meter interface will display the
voltage setting as V-set or V Limit.
The setup method is as follows.
•Method 1: Set by knob and button combination
1. Turn the knob or press the left/right key in the Meter screen until the
parameter area is selected.
2. Press the [Enter] key.
The cursor flashes at this point, indicating that the parameter is in the
state to be modified, as shown in the following figure.
