Explanation Of Controls And Indicators - Urrea UD334 Manual De Usuario

• Voltages greater than 60V DC or
30V AC RMS may cause a serious
shock hazard.
3. EXPLANATION OF
CONTROLS AND INDICATORS
1. CLAMP.
Opens 32mm (1.25 inches) to enclose
conductors.
2. CENTERING MARKS.
Position the conductor within the
jaws at the intersection of the
indicated marks as much as possible
in order to meet the Meter's accuracy
specifications.
3. BARRIER (Hand Guard).
Provides a protective distance and
reduces the danger of touching the
lower jaw opening or the conductor
under test.
4. PEAK HOLD.
E N G L I S H
Captures the peak value to freeze
it in digital display. PEAK HOLD is
available for AC or DC readings only
and cannot be selected when in the
other modes.
5. LEVER.
Opens and closes clamp jaws.
6. FUNCTION SWITCH.
Desribes functions that are selected
by setting the rotary switch.
A - Amperes DC/AC (Autoranges to
the 400A or 1000A range.)
V - Volts DC/AC (Autoranges to the
400V or 600V range).
400Ω - Resistance (Single 400 Ω
range).
kHz - Frequency (Autoranges to
the 4kHz, 40kHz, 400 kHz or 4MHz
range).
- Diode Test.
- Continuity Test.
7. OFF.
Power to the Meter is turned off.
8. DC A ZERO ADJUSTMENT SWITCH.
Used for zero value adjustment when
measuring DC amperes.
9. DISPLAY.
Liquid Crystal Display (LCD).
10. DC/AC.
Toggles between DC and AC.
11. COM (Common Terminal).
The black test lead is plugged into
this terminal for all measurements
except for amperage.
