A16R Industrial Clamp Multimeter User Manual

Product Information

The A16R Industrial Clamp Multimeter is a versatile tool
designed for measuring AC/DC voltage, resistance, continuity,
frequency, and current. It features a 3 3/4 digit large scale LCD
display with a display count of 4000 and a measuring rate of 1.5
times per second. The meter has overload protection of
750Vrms//1000Vdc and input impedance of 1M // less than 100pF. It
is powered by a 9V alkaline battery that has a life of up to 100
hours.

The A16R Industrial Clamp Multimeter is compliant with EU
directives, and the jaw is CAT.IV.600V protected with respect to
earth. The meter also features tactile barriers for hand guards to
ensure safe operation.

Product Usage Instructions

Safety Information: Always follow the
instructions provided for safe operation and service of the Meter.
Failure to observe warnings can result in severe injury or
death.

Off/On: To power on the meter, press any button
(except Hold button) and switch the rotary knob. The meter will
automatically power off after approximately 30 minutes of
inactivity. To disable auto power off, press any button (except
Hold button) and switch the rotary knob.

AC/DC Voltage Measurement: Use the AC V/DC V
function to measure voltage. Ensure that the equipment being
measured is protected by double or reinforced insulation. For DC
measurement, connect the red test lead to the positive (+) terminal
and the black test lead to the negative (-) terminal. For AC
measurement, connect the test leads to the phase line and neutral
line.

Resistance & Continuity: Use the Resistance
and Continuity function to measure resistance and continuity. The
meter has overload protection of 600Vrms and a maximum open circuit
voltage of 3V. The internal sound will activate if the resistance
of the circuit under test is less than 30 approximately.

AC/DC Current Measurement: Use the AC A/DC A
function to measure current. For DC measurement, open the jaw and
place it around the conductor being measured. For AC measurement,
ensure that the jaw is CAT.IV.600V protected with respect to earth.
Do not hold the meter across the tactile barrier for hand
guard.

Frequency Measurement: Use the Hz function to
measure frequency.

Data Hold: Use the Data Hold function to freeze
the displayed value on the LCD display.

Min/Max Hold: Use the Min/Max Hold function to
save and display the minimum and maximum values measured. Press and
hold the MIN/MAX button to return to normal operation.

Peak Hold: Use the Peak Hold function to save
and display the peak maximum and minimum values measured. Press and
hold the PEAK button for 3 seconds to calibrate the meter itself
for accurate measurement. Press and hold PEAK to return to normal
operation.

Back Light: The back light will automatically
turn off after 60 seconds of inactivity.

Battery Replacement: Replace the 9V alkaline
battery when “Replace battery” is displayed or flashes when
pressing a button.

Safety Information
To ensure safe operation and service of the Meter, follow these instructions. Failure to observe warnings can result in severe injury or death.
WARNING
· Avoid working alone so assistance can be rendered. · Do not use test leads or the Meter if they look damaged. · Do not use the Meter if the Meter is not operating properly
or if it is wet. · Use the Meter only as specified in the Instruction card or
the protection by the Meter might be impaired. · Use extreme caution when working around bare
conductors or bus bar. Contact with the conductor could result in electric shock. · Use caution with voltages above 30V ac rms, or 60V dc. These voltages pose a shock hazard. · To avoid false readings, which could lead to possible electric shock or personal injury, replace the battery as soon as the low battery indicator ( ) appears.
