A Word About Safety
52'%+#."2#0'."/#4-+0)5
For your safety, we have added special markings to 
the meter’s panel to remind you of the 
measurement limitations.
The maximum voltage that this meter can 
measure is 1000V DC or 750V AC. The 
maximum current that this terminal can 
measure is 400mA DC and AC.
Caution
: Be extremely careful when 
making high-voltage measurements; DO 
NOT TOUCH TERMINALS OR PROBE 
ENDS.
Caution
: Risk of electric shock! Refer to 
the complete operating instructions.
The meter is protected by double 
insulation.
CAT II
This equipment is rated for 
INSTALLATION CATEGORY II (3600VA 
max.).
To avoid electrical shock or instrument 
damage, do not connect the common input 
terminal (– 
COM
 jack) to any source that 
exceeds 500 volts with respect to earth/
ground.
+10A MAX
FUSED
The maximum current you can measure at 
this jack is 10 amps DC/AC. This jack is 
fuse-protected.
WARNING:
Shock
Hazard if 
guard not 
installed.
The sliding guard on the front of the meter 
protects against electrical shock. Do not 
remove the guard.

• Use extreme care while 
using the meter to mea-
sure current and voltage 
in commercial electrical 
panels. Unlike a home 
AC outlet, a commercial 
electrical panel has tre-
mendous current surge 
potential. This is 
especially true for three-
phase industrial 
electrical panels. A small 
spark from one of these 
panels can cause a 
plasma explosion and 
fire that can severely 
burn you. Do not hold the 
meter while using it. 
• Always wear protective 
leather gloves, a face 
shield, and fireproof arm 
and upper body 
protection while using 
the meter to measure 
current and voltage in 
commercial electrical 
panels. 
• If this equipment is used 
in a manner not specified 
by the manufacturer, the 
protection provided by 
the equipment may be 
impaired. 
• To reduce the risk of fire 
or shock hazard, do not 
expose this product to 
rain or moisture. 
• For indoor use only.
