NON-CONTACT AC VOLTAGE MEASUREMENTS
·
warning! risk of electrocutation! before use, always test the ampclamp 1000
on a known live circuit to verify proper operation.
1. Touch the probe tip to the hot conductor or insert into the hot side of the
electrical outlet.
2. If AC voltage is present, the detector light will illuminate.
∙ The conductors in electical cord sets are often twisted. For best results, rub the
probe tip along a length of the cord to assure placing the tip in close proximidy
to the live conductor.
∙ The detector is designed with high sensitivity. Static electricity or other sources of
energy may randomly trip the sensor. This is normal operation.
BUTTONS
MODE/INRUSH BUTTON [6]
To select
· ACV / Hz / %
· OHM / Continuity / Diode
· °C / °F
· ACA / DCA
RANGE BUTTON [7]
When the meter is first turned on, it automatically goes in AutoRanging. This auto-
matically selects the best range for the measurements being made and is gener-
ally the best mode for most measurements. For measurement situations requiring
that a range be manually selected, perform the following:
1. Press the RANGE button [7]. The “Auto Range” display indicator [H] will turn
off.
2. Press the RANGE button [7] to step through the available ranges until you
select the range you want.
3. Press and hold the RANGE button [7] for approx. 2 seconds to exit the manu-
al ranging and return to Auto ranging. The “Auto Range” display indicator [H]
appears on the LCD display.
PEAK/VFD BUTTON [8]
In the AC voltage mode (with Auto Range indicator [H] visible on the LCD display):
· Short press the PEAK/VFD button [8] to display “----” first and enter the Peak
measurement mode. The maximum PEAK and minimum PEAK voltage can be
measured circularly. Short press the PEAK/VFD button [8] to switch between
Max and Min. Long press the PEAK/VFD button [8] to return to Auto.
· Long press the PEAK/VFD button [8] to enter the VFD function measurement. In
the VFD mode, the voltage value of the variable frequency drive device can be
measured. Long press the PEAK/VFD button [8] again to return to Auto.
The measured values of “PEAK” and “VFD” are for reference only.
REL/BACKLIGHT BUTTON [4]
· REL for DCA and Capacitance Zero & Offset adjustment.
· Long press this button to turn on the backlight of the LCD display. Long press
again to turn off the backlight.
DATA HOLD/FLASHLIGHT BUTTON [10]
· To freeze the LCD meter reading, press the DATA HOLD button [10]. The data
hold button is located on the right side of the Ampclamp 1000. While data hold
is active, the “H” (Data Hold symbol [M]) is visible on the screen. Press the DATA
HOLD button [10] again to return to normal operation.
· Long press the DATA HOLD button [10] to turn ON and OFF the flashlight.
