2. Safety
This symbol adjacent to another symbol, terminal or operating device
indicates that the operator must refer to an explanation in the User
manual to avoid personal injury or damage to the meter.
This WARNING symbol indicates a potentially hazardous situation that
could result in death or serious injury if not avoided.
This CAUTION symbol indicates a potentially hazardous situation that
may result in damage to the product if not avoided.
Terminals with this marking must not be connected to voltage
exceeding 600 V in DC or AC in respect to earth.
Terminals with this marking can be subjected to particularly high
voltages during normal use. For maximum safety, the meter and the
leads should not be handled while these terminals are energized.
Indicates electrical protections with double insulation.
1.
Overvoltage category I
Equipment with CAT I protection is only to be connected to circuits where protection
measures for limiting the transient over-voltages to acceptably low values are
observed.
NOTE:
Examples include protected electronic circuits.
2.
Overvoltage category II
Equipment with CAT II is can be connected to fixed installations with overvoltage
protection in place.
NOTE:
Examples include household, office, and laboratory appliances.

3.
Overvoltage category III
Equipment with CAT Ill can be used as part of fixed installations. It must contain its
own overvoltage protection.
NOTE:
Examples include switches in the fixed installation and some equipment for industrial
use with permanent connection to the fixed installation.
4.
Overvoltage category IV
Equipment with CAT IV is used at installation connection to the network.
NOTE:
Examples include electricity meters and primary over-current protection equipment.
The meter has been designed to be used safely, but must always be operated with
caution. Rules for safe operation are the following.
DO NOT use with voltage or current exceeding the specified maximum.
Input Protection Limits

Maximum Input
Voltage DC or AC
600 VDCRMS / VACRMS

Duty Cycle, Diode test, Continuity
Current AC or DC
10 A
Surge Protection:6kV peak per IEC 61010
USE EXTREME CAUTION when working with high voltages.
DO NOT measure voltage if voltage on the "COM" input jack exceeds 600V
above earth.
NEVER connect the meter leads across a voltage source while the function switch
is in the current, resistance, or diode mode. Doing so can damage the meter.
ALWAYS discharge filter capacitors in power supplies and disconnect the power
when making resistance or diode tests.
ALWAYS turn off the power and disconnect the test leads before opening the
covers to replace the fuse or batteries.
NEVER operate the meter unless the back cover, the battery, and fuse covers are
in place and fastened securely.
If the equipment is used in a manner not specified by the manufacturer, the
protection provided by the equipment may be impaired.

Cursor soft buttons
Use navigational stick to select item in a menu, adjust display contrast, scroll through
information, perform data entry, or enter one of the data modes:
Up navigational button enters Relative zero function; compare new result
to the previous.
Left navigational button enters Maximum function; only save when new
result is higher than previous.
Right navigational button enters Peak mode; fast capture of the highest
value.

4. DMM Setup and Measurements
CAUTION:
Do not measure DC voltages on a motor while the circuit is being
switched ON or OFF. Large voltage surges may occur that can
damage the meter.
Set the rotary function switch to the VDC position.
Insert the black test lead banana plug into the negative COM
jack.
Insert the red test lead banana plug into the positive V jack.
Read the voltage in the display.
CAUTION:
Do not measure DC voltages on a motor while the circuit is being
switched ON or OFF. Large voltage surges may occur that can
damage the meter.
Set the function switch to the VDC position.
Insert the black test lead banana plug into the negative COM jack. Insert the red
test lead banana plug into the positive V jack.
Press the MODE key to switch the V AC+DC Voltage
function
Read the AC+DC voltage in the display.
WARNING: Risk of electrocution. The probe tips may not
be long enough to contact the live parts inside some
240V outlets for appliances if the contacts are recessed
deep. Therefore, the meter may read 0 on a live outlet.
Make sure the contact is made before assuming no
voltage is present.
CAUTION:
Do not measure DC voltages on a motor while the circuit
is being switched ON or OFF. Large voltage surges may
occur that can damage the meter.
Set the rotary function switch to the VAC position.
Insert the black test lead banana plug into the negative COM jack. Insert red test
lead banana plug into the positive V jack.
Read the voltage in the main display
Set the rotary function switch to the Hz% position.
Insert the black test lead banana plug into the negative COM jack. Insert the red
