UEi Test Instruments DL235 - Manual (Page 2)

• Always disconnect the live test lead before disconnecting the
common test lead from a circuit
• When measuring high voltage, disconnect the power source before
making test lead connections. Connect the test leads to the meter
first then to the circuit under test. Reapply power
• If any of the following indications occur during testing, turn
off the power source to the circuit under test:
• Arcing
• Flame
• Smoke
• Extreme Heat
• Smell of Burning Materials
• Discoloration or Melting of Components
• Read the safety precautions associated with the equipment being
tested and seek assistance or advice when performing
unfamiliar tasks.
• Keep your fingers away from the test lead metal probe contacts
and bus-bars when making measurements - Always grip the
instrument and test-leads behind the hand guards (molded into
the probes)
• In the event of electrical shock, ALWAYS bring the victim to
the emergency room for evaluation, regardless of the victim’s
apparent recovery - Electrical shock can cause an unstable heart
rhythm that may need medical attention

Introduction
The DL235 combines the speed and versatility of a high resolution analog
display with the precision of a digital meter. This meter measures the
True RMS value of Alternating Current (AC) over from 0.3A to 700A. AC
measurements are from 10 Hz to 1 KHz and frequency measurements are
from 0.5 Hz to 10 KHz.
Clamp meters that measure average current flow are inaccurate for
non-linear currents and their measurements may have some differences
from those obtained using this meter.
The DL235 can also measure frequency while measuring current flow
s i m u l t a n e o u s l y. AC and DC voltages and resistances can be measured
and also continuity check is possible with this meter.
Features include
• True RMS
• Soft mode reduces fluctuations in amp
• Crest mode will display 1/2 wave peak
• MIN/MAX record
• 3-3/4 digit 4000 count LCD display
• Auto or manual ranging
• Data hold
• Low battery indication
• Auto power off
• Ruggedized to withstand a 10’ drop
Safety Notes
Before using this meter, read all safety information carefully. In
this manual the word "WARNING" is used to indicate conditions
or actions that may pose physical hazards to the user. The word
"CAUTION" is used to indicate conditions or actions that may
damage this instrument.
WARNING!
Exceeding the specified limits of this meter is dangerous and can
expose the user to serious or possibly fatal injury.
• DO NOT attempt to measure any voltage that exceeds 600 volts
with this meter - UEi offers numerous alternatives for measuring
high voltage and current
• Voltages above 60 volts DC or 25 volts AC may constitute a
serious shock hazard
• DO NOT attempt to use this meter if either the meter or the test
leads have been damaged. Send unit in for repair by a qualified
repair facility
• Test leads must be fully inserted prior to taking measurements
• Always turn off power to a circuit (or assembly) under test before
cutting, un-soldering or breaking the current path. Even small
amounts of current can be dangerous
