2Overview
This chapter will give you an overview of M3500A’s basic features and
guide you through the basics of M3500A digital multimeter. Users will
become familiar with those features after reading this chapter.
2.1 Setting up Your M3500A Digital Multimeter
The purpose of this section is to prepare users for using M3500A DMM.
You may want to check if you have all the parts with your multimeter. All
our products are handled and inspected professionally before shipping
out 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 users have any doubt about
their products, they are encouraged to contact their local service
representative.
2.1.1 To adjust the handle
You may adjust the carrying handle to suit your needs. The following
figures show you how to adjust the handle.
I. Taking off the handle from the Multimeter
【Step 1】(Turn up the handle)
Pull slightly outward on both sides of the handle and slowly rotate it up as
shown in Figure 1-1.

Figure 1-1
【Step 2】(Pull out the handle)
When the handle is turned up to 90° with the multimeter, pull out the
handle from the multimeter as shown in Figure 1-2.

Ⅱ. Adjusting the position for your convenience
Here are some example positions to suit users’ needs.
【Position 1】
The default position is for packing as shown in Figure 1-3。

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 M3500A 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.
【Step 1】
Verify that the meter is disconnected as shown in Figure 2-1.

Figure 2-1
【Step 2】
Open the voltage setting selector cap as shown in Figure 2-2. (You
might need a screwdriver to do so.)
Figure 2-2
【Step 3】
Remove the red voltage setting selector from the right middle seam as
shown in Figure 2-3. (You might need a screwdriver to do so.)

【Step 4】
Turn it over to 220V position as shown in Figure 2-4.
Figure 2-4
【Step 5】
Insert the voltage setting selector back into the socket and close the cap
as shown in Figure 2-5.

2.1.2.2 To change the fuse
Warning! Before replacing the power-line fuse, make sure the
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.
【Step 1】
Verify that the meter is disconnected as shown in Figure 2-6.

【Step 3】
Remove the red voltage setting selector from the right middle seam as
shown in Figure 2-8. (You might need a screwdriver to do so.)
