Safety Requirement

General Safety Summary

Be aware of the following safety precautions to avoid injury and prevent
damage to the product or any product connected to this product. To avoid
possible hazards, be sure to use this product in accordance with the
regulations.

Use the correct power cord.

You are only allowed to use the specified power cord approved by the country you are
currently in.

Ground the product.

This product is grounded through the protective grounding wire of the power
cable. To avoid electric shock, please ensure that the grounding terminal of the

power cable is connected to the protective grounding terminal reliably before
connecting to any input or output terminals of the product.

View all terminal ratings.

To avoid fire and excessive current shock, please check all the ratings and
markings on the product and consult the product manual for details of the ratings
before connecting the product.

Use appropriate overvoltage protection.

Ensure that no overvoltage (such as voltage caused by lightning) reaches to this
product. Or else the operator may expose to danger of electric shock.

Do not open the lid while operating.

Do not operate the product with the machine case open.

Use appropriate fuse.

Only specified fuses are allowed.

Avoid exposed circuits.

After powering on, do not touch exposed splices and components.

Do not operate if the product is suspected to be out of order.

If you suspect there is something wrong with the product, please contact maintenance
personnel authorized by Hantek for testing. Any maintenance, adjustment or
replacement of components must be performed by repairmen authorized by Hantek.

Maintain good ventilation.

Poor ventilation may cause the temperature of the instrument rising and then lead to
damage to it. Good ventilation should be maintained when using, and the vents and fans
should be checked regularly.

Do not use in a humid environment.

To avoid short circuit and electric shock, do not operate the instrument in damp
environment.

Do not operate in a flammable and explosive environment.

In order to avoid damage to the instrument or personal injury, do not operate the
instrument in a flammable and explosive environment.

Please keep the surface of the product clean and dry.

To avoid dust and moisture in the air affecting the performance of the instrument, please
keep the surface of the product clean and dry.

Anti-static protection.

Static electricity may cause damage to the instrument. It would be better to test the

instrument in anti-static area. Before connecting the cable to the instrument, the inner
and outer conductors should be grounded briefly to release the static electricity.

Pay attention to carrying safety.

To avoid the instrument sliding in the process of carrying, causing damage to the keys on
the panel, the knobs or interfaces, please pay attention to carrying safety.

Interference tests for all models comply with Class A standards, based on EN
61326:1997 +A1+A2+A3

Input terminal protection limits.

The protection limits are defined for the input terminals:

1. Main input (HI and LO) terminals.

The HI and LO input terminals are used for voltage, resistance,
capacitance, connectivity, frequency, and diode test measurements. These
two terminals define the following two protection limits:

1) HI to LO protection limit. The HI to LO protection limit is 1000 VDC or

750 VAC, which is also the maximum measurable voltage. This limit
can also be expressed as a maximum of 1000 VPK.

2) Lo to the ground protection limit. LO input terminals can safely "float" to a

maximum of 500 Vpk relative to the ground.

The HI terminal protection limit is up to 1000 VPK relative to the ground.
Therefore, the sum of the "floating" voltage and the measured voltage must not
exceed 1000 VPK.

2. Sampling terminal.

1) The HI and LO Sense terminals are used for DCV proportional

measurements, four-wire resistance and temperature measurements.
The measurement limit for all terminal pairs is 200 Vpk: LO Sense to
LO input, HI Sense to LO input, HI Sense to LO Sense.

3. Current input terminal.

The measurement limit is 10.5A (DC or AC) when using the 10A-current­input terminal and the LO terminal. The measurement limit is 3.1A (DC or
AC) when using 3A-current-input terminal and the LO terminal.

Note:

To avoid blowing the fuse or damaging the multimeter, please follow the
instructions below to use the current input terminals.

1) When performing current test measurements, be sure to select an

appropriate current input terminal according to the expected current size
before switching on the multimeter power.

2) The maximum current input to 10A terminal shall not exceed 10.5A, otherwise, the

internal fuse will be blown; The maximum current input to 3A terminal shall not
exceed 3.1A, otherwise, the rear panel current input fuse will be blown.

IEC measurement class II overvoltage protection.

To avoid electric shock, the HDM3000 digital multimeter provides overvoltage
protection for line-voltage mains connections meeting both of the following
conditions:

1. The HI and LO input terminals are connected to the mains under Measurement

Category II conditions, defined below.

2. The maximum line voltage of the power mains is 300 VAC.

Warning: IEC II includes electrical devices connected to a mains at an
outlet on a branch circuit. These devices include most small appliances, test

equipment, and other devices plugged into branch sockets.
The HDM3000 can be used to make measurements where the HI and LO input
terminals are connected to power mains (up to 300 VAC) in these devices, or
to branch sockets themselves. However, the HI and LO input terminals of the
HDM3000 cannot be connected to power mains in permanently installed electrical
devices, such as main circuit breaker switchboards, sub-panel disconnected box
nor wired motors. These devices and circuits are prone to be in excess of the
HDM3000 protection limit.

Note: Voltages over 300 VAC can only be measured in circuits that are
disconnected from the main power line. However, there are also transient

overvoltages in circuits that are disconnected from the mains. The HDM3000 can
safely withstand occasional transient overvoltage up to 1500 Vpk. Do not use
the device to measure circuits whose transient overvoltage may exceed this
value.

1. Connect the terminals and the current input fuse.

The multimeter uses two types of fuses to provide input protection for small and large

current ranges. The internal fuse provides the maximum protection limit of 10.5A for

the input of large current range. The fuse will be blown when the input current

exceeds 10.5A. The rear panel current input fuse provides the maximum protection

limit of 3.1A for small current range input, and the fuse will be blown when the input

current exceeds 3.1A. The multimeter is equipped with a high current input fuse when

leaving the factory. If you need to replace the small current fuse, please do it in the

following way:

1) Turn off the power of the multimeter and unplug the power cord.

2) Use the straight screwdriver to push in slightly and rotate along the direction shown

in the picture to pull out the fuse holder.

3) Replace specified fuses.

4) Put the fuse holder into the card slot.

Note: the large current input fuse is located inside the instrument and is not allowed to

be replaced by the user. If needing replacement, please contact Qingdao Hantek

Electronic Co., Ltd.

You can use the VMC OUT soft key to set the edge slope of the VM Comp (voltmeter

complete) output on the rear panel of the instrument. This connector emits a signal

whenever completing a measurement, allowing you to send signals to other devices in

the measurement system.

6. External trigger input

You can trigger a multimeter by adding a trigger pulse to the [Ext Trig] connector. At

this point, you need to select an external trigger source.

7. LAN interface
