Features - IDEAL 61-920 Mode D'emploi

DANGER
• Do not use the instrument on a circuit where electrical potential exceeds 300VAC.
• Do not use the instrument during an electrical storm or in wet weather.
• Do not use the instrument in the presence of flammable gas, dust or vapor.
• Wear insulated protective gear to avoid electrical shock.
• Use caution where the equipment under test has exposed metal parts.
• Never attempt to use the instrument if its surface or your hands are wet.
• Do not use meter if it operates abnormally as protection may be impaired.
• Do not use around explosive gas, dust, vapor, or in damp or wet environments. Do not
submerge or expose the meter to water and do not use if the meter has ever been exposed to
water or other fluids.
• Do not exceed the maximum allowable input of any measuring range.
• Do not use the instrument on a circuit over 30AAC. If "
measurement immediately. Remove meter from conductor.
• Never open the battery cover during a measurement.
• When the transformer jaws are worn to the wear line (see the figure below), stop the use of
the instrument.
WARNING
• Do not use the instrument if any abnormal conditions, such as a broken cover or exposed
metal parts are present on the instrument.
• Do not install substitute parts or make any modification to the instrument.
• Do not try to replace the batteries if the surface of the instrument is wet.
• Always turn off the instrument before opening the battery cover for battery replacement.
• Always be sure to keep your fingers and hands behind the safety barrier. (see figure below)
Otherwise, user may be exposed to the danger of electrical shock.
• Do not submerge or expose the meter to water and do not use if the meter has ever been
exposed to water or other fluids.
CAUTION
• Press the Function button and confirm the appropriate function is selected before starting a
measurement.
• Do not expose the instrument to the direct sun, high temperatures and humidity or dew.
• Press the Power button and turn off the instrument after use. When the instrument is not in
use for a long period of time, place it in a storage after removing the batteries.
• Use a damp cloth with mild detergent for cleaning the instrument. Do not use abrasives
or solvents.
• Do not drop. Precisely adjusted transformer jaws will be damaged.
• Keep jaw tips clear of debris.

2. Features

The 61-920 is a digital clamp-on ground resistance tester. The instrument can measure
the ground resistance by simply clamping around the ground conductor, ground rod or
equipment ground conductor.
The 61-920 also measures leakage AC current up to 30AAC.
• Wide measuring range (Auto-ranging)
Ground resistance Max. 1200Ω
AC current Max. 30A
• Noise check function senses current on the ground electrode or ground wire and
displays NOISE on the LCD display.
• True RMS feature accurately measures AC current even with distorted waveforms due to
harmonics.
• Auto power-off feature powers the meter down automatically after 10 minutes of
non-use to conserve battery power.
• Data hold feature is used to capture and hold a reading in the LCD display.
• Continuity buzzer function provides an audible warning to the user when the
measurement result is 10Ω or less.
• Backlight feature illuminates the display for working in dimly lit areas.
• Memory save feature records and displays the measurement result.
• Complies with IEC61010-1: 2001 (CAT.IV 300V Pollution degree 2),
IEC61010-2-032: 2002 safety standards.
• This instrument is protected by double or reinforced insulation
Min. resolution 0.01Ω
Min. resolution 0.1mA
