Security information
The instrument is designed to comply with the IEC 61010 safety
standard and has been thoroughly tested for safety prior to
shipment. However, if it is used improperly, it may cause injury or
death and damage the instrument. Be sure to read through this
manual and its precautions before use. Our company does not
assume any responsibility for accidents and injuries not caused by
defects in the instrument itself.
Safety signs
This manual marks the relevant signs for safe operation of the
instrument. In order to ensure the safety of the instrument and its
users, please read the following safety signs and operating
precautions carefully before use.
Indicates very important message in this manual.
When the symbol is printed on the instrument, refer
to a corresponding topic in the Instruction Manual.
Indicates DC (direct current)
Indicates a fuse
Indicates earth terminal

In this manual, the risk seriousness and the hazard levels are
classified as follows:
Indicates an imminently hazardous
situation that will result in death or
serious injury to the operator.
Indicates a potentially hazardous
situation that will result in death or
serious injury to the operator.
Indicates a potentially hazardous
situation that may result in minor or
moderate injury to the operator or
damage to the instrument or
malfunction.
Indicates functions of the instrument
or relative suggestion of a correct
operation.
Accuracy
We define measurement tolerances in terms of f.s. (full scale), rdg.
(reading) and dgt. (digit) values, with the following meanings:
f.s. (Maximum display value)
This is usually the maximum display value. In the instrument, this
indicates the currently used range.
rdg. (Reading or displayed value)
The value currently being measured and indicated on the
measuring instrument.
dgt. (Resolution)
The smallest displayable unit on a digital measuring instrument,
i.e., the input value that causes the digital display to show a “1”.

Usage Notes
Installation environment
Operating temperature and humidity ranges:
0°C to 40°C, 80%RH or less (no condensation)
Temperature and humidity range to ensure accuracy:
23 ± 5°C, 80%RH or less (no condensation)
To avoid failure or damage to the instrument, do not place the
tester in the following places:
⚫Places where the sun is shining directly at high temperatures
⚫Places exposed to large amounts of dust particles
⚫Places exposed to water, oil, chemicals, or solvents
⚫Places where corrosive or explosive gases are flooded
⚫Places with strong electromagnetic fields or electromagnetic
radiation
⚫Places where mechanical vibration is frequent
Checking before use
Before the first use of the instrument, verify that the operation is
normal to ensure that there is no damage occurred during storage
or shipping. If you find any damage, please contact us.
Before using the instrument, check
that the coating of the test lead or
cable is not torn and does not expose
metal parts. If the test wire is not
insulated and the conductor is
exposed, there may be a risk of
electric shock using this instrument,
please contact us in this case.

10
Use of instruments
Measurement considerations
To avoid electric shocks and short
circuits, the following procedures
must be followed:
Please do not wet this instrument or
measure with wet hands. Otherwise,
it will lead to electric shock accident.
Do not modify, disassemble or repair.
Otherwise, it will cause fire, electric
shock accident or personnel injury.
To avoid electric shock, do not
disassemble the instrument electronic
enclosure. There are high pressure
and high temperature parts inside the
instrument during operation.
Do not place the instrument on an
unstable or slanted surface. It may
drop or fall, causing injury or
instrument failure.
To avoid corrosion or damage to the
instrument due to battery leakage,
remove the batteries from the
instrument if it is to be kept in storage
for an extended period.
Be sure to turn the power off after
using it.

11
In order to prevent damage to this
instrument, please avoid vibration
and collision during handling and use.
Pay special attention to the collision
caused by falling.
Do not connect measuring terminals
to EX.I/O terminals and
communication terminals to avoid
damage to this instrument.
Use of test leads and cables
For safety reasons, the original test
line or test line selection should be
used when testing.
To avoid damaging the cables, do not
bend or pull the base of cables and
the leads.
The front end probe of the test leads
are sharp and careful not to be
scratched.
To avoid damage to the test leads,
when plug/pull the test line, don’t
hold the cable but connector.

Chapter I Overview
1.1 Introduction
HT3530 is an insulation resistance tester controlled by high
performance microprocessor. Seven range test, output voltage
continuously adjustable, can test 500Ω~9.9* PΩ resistance,
maximum display 99999, test speed up to 5 times per second.
Instrument has professional sorting function, with 10 sets of
storage data, a variety of sorting sound settings, equipped with
Handler interface, used in automatic sorting system to complete
automatic pipeline testing. Built-in RS232 interface and LAN
interface for remote control and data acquisition and analysis.
