Safety Information - Circuit-test DMR-2400 User Manual

SAFETY INFORMATION

This meter is CUL and UL approved. This meter is designed to be safe un-
der the following conditions: indoor use, altitude up to 2000m, temperature
5°C to 40°C, maximum relative humidity 80% for temperatures up to 31°C
decreasing linearly to 50% relative humidity at 40°C and rated pollution
degree 2. Caution and proper guidelines must be followed for personal
and product safety. Read this instruction manual carefully and completely
before using the meter. Lack of caution or poor safety practices can result
in serious injury or death.
• This meter is not recommended for high voltage industrial use; for
example, do not use for measurement on 440VAC or 600VAC industrial
power mains. The unit is intended for use with low energy circuits up to
600VDC / 600VAC or high energy circuits up to 250VAC / 250VDC only.
• Use caution when working above 60VDC or 30VAC RMS as these volt-
ages pose a shock hazard.
• Always consider circuits to be energized. Never assume any equipment
to be de-energized.
• Always start with power off. Set the function switch to the correct setting
before making any measurements and do not change position of the
function switch during measurements.
• Never connect unit to AC or DC powered circuits when the function
switch is set to resistance, diode check or continuity ranges.
• Always disconnect the power when performing resistance, diode or
capacitance tests. Discharge capacitor before testing.
• Disconnect the live/positive test lead (red) prior to disconnecting the
common/negative test lead (black).
• When ʻLO BATʼ appears on the display, change both batteries to
achieve more accurate readings.
• Disconnect test leads from the meter before removing the batteries or
the fuse.
• Do not operate the unit unless the case is completely closed.
• When using the test probes always keep fingers behind the finger
guards. Never touch the exposed probe tip.
• Always inspect the instrument, test leads and other accessories for
damage prior to use.
• Use only UL recognized test leads (included with this meter).
