Peak Hold Function - Urrea UD334 Manual De Usuario

This value is variable according to the
location measuring DC Amps.
Thus, this non-zero DC Amps value
should be zeroed by using the DC
A Zero Adjustment switch before
clamping around a DC current
carrying conductor.
When measuring a DC current-
carrying conductor, the DC Amps
value has a positive or negative
polarity according to the direction of
DC current flow. The value is positive
when the current flows through the
conductor in the forward-moving
direction of a right-hand threaded
screw.
Use the arrow direction mark on the
insulated guard of the lower jaw
opening to identify the direction of
DC current flow.
Follow these steps to measure DC
Amps:
1. Set the function steps to measure
DC Amps.
2. Toggle DC/AC switch to select DC.
(AC disappears on the LCD.)
3. Set the Meter display zero value
by using the DC A Zero Adjustment
switch.
4. Press the lever to open the clamp
jaws and clamp around a conductor.
(If necessary; use the arrow direction
mark to identify the direction of DC
current flow.)
5. Read the display.
• MEASURING AC/DC VOLTAGE
Follow these steps to measure AC/DC
voltages:
1. Insert the red test lead into the
VΩHz input terminal and the black
test lead into the COM terminal.
2. Set the function switch to V.
3. Toggle DC/AC switch to select DC
E N G L I S H
or AC voltage measurement function.
4. Touch the test probes to the test
points and read the display.

• PEAK HOLD FUNCTION

For all AC or DC readings, the PEAK
reading can be held in the display
when the Peak Hold button has been
activated. However, when in Peak
Hold Mode, the product will not read
above 400 Amps, or 400 Volts.
When the input exceeds 400, the LCD
reads "OL".
1. Ensure that the Peak Hold button
has not been activated.
2. Make AC or DC Amperes or Volts
measurement using the Meter.
3. Press and release the Peak Hold
button then the Meter is still
connected to the circuit.
4. The Meter will hold the PEAK
reading in the display until the Peak
Hold button is pressed and released
again or the function switch is set to
another position.
NOTE: When using the Peak Hold function
