The compact precision DMM with AutoTect
™
and VolTect
™
Compact Digital Multimeter with AutoTect
™
and VolTect
™
• AutoTect
™
feature directs
the meter to know if it is
measuring ac volts, dc
volts or resistance with
no user interface
• The AutoTect
™
feature has
lower input impedance
which zeros out ghost
voltages
• Measures ac/dc current,
capacitance, frequency,
continuity with beeper
plus includes Voltect,
™
a built-in, non-contact
voltage detector
• Complete user protection
with full safety ratings of
CAT III 300 V, CAT II 600 V
and UL and CSA listing
• Large oversize digital
display
• Protective silicon holster
included, attached test
leads, battery, deluxe
carry case and manual
• One-year, no-hassle
warranty
The ultimate shirt-pocket sized
meter. Only 3/8" thick and less than
3 oz in weight with full functionality
offering ac and dc voltage to 600 V,
ac and dc current to 2000 µA, resist-
ance to 6 Megohm, capacitance to
2000 µF, frequency to 30 kHz, diode
test and contin
uity w/beeper. It
also offers VolTect,
™
a built-in,
non-contact voltage detector for
ac voltages.
Another key feature is AutoTect,
™
which automatically selects
between ac voltage, dc voltage or
resistance measurement based on
the test point to which the leads are
connected. Fully autoranging, this
meter offers nine different measure-
ment functions plus features that
are usually found in much more
expensive and larger meters.
The digital display is oversized
with large digits and unit icons in
the displa
y. In spite of its size, this
meter is fully safety rated to CAT III
300 V, CAT II 600 V and is UL listed.
No other meter this small offers
such performance and high safety
ratings. Includes a silicone protec-
tive holster, deluxe carrying case,
attached test leads, battery and
manual.
