UNI-T UT70A User Manual

Operating Manual of UT70A Multimeter
HIGHLIGHTS
UT70A Multimeter is a hand-held digital multimeter with
advanced design, multiple functions, novel figuration,
large display screen and reliable performance. This meter
is fully capable to measure voltage and current both AC
and DC, resistance, capacitance, inductance, temperature,
frequency, forward voltage drop of diode, transistor hFE
and continuity test, TTL LOGIC level measurement. It
has some extraordinary functions such as holding the
measured data and maximum value, providing backlight
display in a dim condition, displaying polarity, over-range,
low battery, and units icons, and full overloading protection
and automatic power off.
NOTES FOR SAFE USAGE
1) CE Version: The Meter complies with the standards
IEC61010-1:in pollution degree 2, overvoltage category
CAT III 1000V, CAT IV 600V and double insulation .
UL Version: The Meter complies with the standards
UL61010B-1, in pollution degree 2, overvoltage
category CAT II 1000V and double insulation.
CATII: Local level, appliance, PORTABLE EQUIPMENT
etc., with smaller transient overvoltages than Installation
CategoryIII.
CATIII: Distribution level, fixed installation,with smaller
transient overvoltages than CAT IV.
CAT IV: Primary supply level, overhead lines,
cablesystems etc.
2) Make sure the insulation of the meter in good condition,
no damage and break before use.
3) Don’t use at all unless the back case is in place or
there is danger of electric shock.
4) Battery should be replaced to ensure an accurate
measurement when " " appears on LCD.
