1.5 Safety Information
Caution! Please read through the following safety information
before using the product.
To avoid possible electric shock or personal injury, please read and
follow these guidelines carefully:
Follow the guidelines in this manual and DO NOT use the Meter if
the case is damaged. Check the Meter case and terminals, and
7
make sure all the devices are in the proper positions.
Do not apply excessive voltage to the Multimeter. Apply voltage
within the rated range only.
Use caution when measuring voltages above 30 V RMS, 42 V peak,
or 60 V DC. These voltages pose an electric shock hazard.
When using the probes, always keep your fingers behind the finger
guards.
Always connect the common test leads (black) before connecting
the live test leads (red), and disconnect the live test leads (red)
before disconnecting the common test leads (black). This will
reduce the chance of an electric shock.
Disconnect circuit power and discharge all high-voltage capacitors
before testing resistance, continuity, diodes or capacitance.
If you need to open the Meter case or replace any parts, read the
instruction in this manual first. You must be a qualified personnel to
perform this action.
When replacing fuses, use only the same type and same rating as
specified.
Do not try to operate the Meter if it is damaged. Disconnect the
power from the equipment and consult the local service
representative. Return the product to ATTEN.EU service department
if necessary.

Overview
This chapter will give you an overview of ATM3500A’s basic features
and guide you through the basics of ATM3500A digital multimeter. You
will become familiar with those features after reading this chapter.
2.1 Setting up Your ATM3500A Digital
Multimeter
You may want to check if your multimeter is ready for measurement.
In fact, all of the ATTEN.EU products are inspected perfectly before
being shipped to our customers. If you find any damaged or missing
parts, please contact your local service representative immediately and
do not attempt to operate the damaged product. If having any doubt
of your products, you are encouraged to contact the local service
representative.

2.1.2 To connect the power
Check the power-line voltage on the rear panel to see if voltage setting
is correct for your area. Change the setting if it is not correct or the
fuse is broken. Please follow the steps below.
2.1.2.1 To convert the voltage
Warning! In some areas, the power supplied voltage is 240V or
120V; in others, the power supplied voltage is 220 V or 100 V. Please
refer to your local power supplied voltage to see if you have the right
setting.
Warning! Before changing the setting, make sure the multimeter
is disconnected from the AC power. An incorrect voltage setting may
cause severe damage to your instrument.
Warning! The power cord supplied with ATM3500A contains a
separate ground wire for use with grounded outlets. When proper
connections are made, instrument chassis is connected to power line
ground through the ground wire in the power cord. Failure to use a
grounded outlet may result in personal injury or death due to electric
shock.
Suppose your condition is in AC 100V and you want to convert the
voltage to the 220V. Follow these steps to change the voltage setting.

multimeter is disconnected from the AC power. You must be a qualified
personnel to perform this action.
Warning! For continued protection against fire or instrument
damage, only replace fuse with the same type and rating. If the
instrument repeatedly blows fuses, locate and correct the cause of the
trouble before replacing the fuse.
Verify that the power-line fuse is good. Replace the fuse if it is
damaged. Use only the same type and same rating fuse noted on the
rear panel. Please follow the steps below to change the fuse.
