INSTRUCTION MANUAL
Introduction
The DL297T is an autoranging, true RMS digital multimeter that’s
packed full of functions, features, and outstanding value. This meter is
unbeatable for portable power generator maintenance and electrical
troubleshooting. Use temperature and frequency functions along with
the process monitoring features to take on those tasks that you face
daily in your technologically advanced workplace.
Features include
• 1000 V DC / 750 V AC
• UL and CE listed
• Measures volts, amps, resistance, temperature, frequency
and continuity
• Compare mode (CMP) for quick Go/No-Go tests
• HI/LO allows you to quickly recall upper and lower limits
• Relative mode (REL) displays change of value
• Record mode stores minimum, maximum and average
values for 24 hours
• Hold features freezes the data on the display
• Fast responding analog bar-graph
• Low battery indicator and auto power-off with manual overdrive
• Ruggedized to withstand a ten foot 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.
• Always follow industry standard safety practices including protective
clothing, gloves and safety glasses when appropriate
• Do not attempt to measure any voltage that exceeds the
ca t e g o ry b ased rating of this meter
• Do not attempt to use this meter if either the meter or the test
leads have been damaged. Turn it in for repair at a qualified
repair facility
• Ensure meter leads are fully seated by making a quick continuity
check of the leads prior to making voltage measurements
• Keep your fingers away from the test lead’s metal probe
contacts when making measurements. Always grip the leads behind
the finger guards molded into the probes
• Use a current clamp adapter when measuring current that may
exceed 10 amps. See the accessories in UEi’s full-line ca t a l o g
• Do not open the meter to replace batteries or fuses while the
probes are connected
WARNING!
Exceeding the specified limits of this meter is dangerous and can
expose the user to serious or possibly fatal injury.
• DO NOT try to measure any voltage that exceeds 1000 DC or
750 AC volt peak
• Voltages above 25 volts AC or DC may constitute a
serious shock hazard
• Always turn off power to a circuit (or assembly) under test
before cutting, unsoldering, or breaking the current path Even small amounts of current can be dangerous
• Always disconnect the live test lead before disconnecting the
common test lead from a circuit
• 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
• Higher voltages and currents require greater awareness of
physical safety hazards - Before connecting the test leads; turn
off power to the circuit under test; set the meter to the desired
function and range; 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
CAUTION!
Do not attempt to remove the meter leads from the circuit under test.
The leads, the meter, or the circuit under test may have degraded to
the point that they no longer provide protection from the voltage and
current applied. If any of these erroneous readings are observed,
disconnect power immediately and recheck all settings and connections

Operating Instructions
Disabling the Auto Power Off Function
To disable the auto power off function for long-term measurements,
turn the meter on while holding down the “HOLD” push-button. Auto
power-off will be disabled until the meter is manually turned off.
“CMP” Mode
Set the function and range switch to the desired location and turn
on the meter. Depress the “CMP” push-button. You are now in the
compare mode.
Now press the “EDIT” push-button. The “1” at the right side of the
LCD will begin to blink and the arrow at the right of the bar graph will
come on. This indicates that the value you put in will be the highest
acceptable reading. Using the arrow push-buttons found on the “CMP,
REL, % and REC” buttons, enter the HI value that you want your
readings to be compared to.
Once the value is entered, press the “HI/LO” push-button. Now the
arrow at the left of the bar graph will come on. This indicates that the
value you put in will be the lowest acceptable reading. Using the
arrow push-buttons, enter the LO value that you want your readings
compared to.
Press the “EDIT” push-button to exit the mode. From this point on, all
readings will be compared to the stored values and displayed on the
LCD in one of three ways:
• “LO” - The reading is lower than the LO stored value
• “PASS” - The reading is between the stored values
• “HI” - The reading is higher than the HI stored value
“REL” Mode
Set the function and range switch to the desired location. In the “REL”
mode, the meter displays the difference between the stored value and
the measured value.
Turn on the meter and press the “REL” push-button. “REL” will appear
on the LCD and the bar graph pointer will be positioned at the center of
the scale.
Press the “EDIT” push-button to exit the mode.
All measurements will be displayed as the difference between the stored
value and the measured value. Negative readings are lower than the
stored value. Positive readings are higher than the stored value. Pushing
the “REL” button again exits the mode.
“%” Mode
Set the function and range switch to the desired location. In the “%”
mode, the meter displays the difference in percentage between the
stored value and the measured value.
Turn the meter on and press the “%” push-button. The “%” sign will
appear on the LCD and the bar graph pointer will be positioned at zero
on the scale.
Press the “EDIT” push-button. Using the arrow buttons, enter the value
you want the readings displayed as a percentage of. Once the value is
entered, press the “EDIT” push-button to exit the mode.
C o n t rols and Indicators
1. Digital Display: Readings are displayed on a 4-4/5 digit,
50,000 count (primary display) and 5,000 count
(secondary display).
2. “CMP”, “REL” and “%” Push-buttons: These three functions
allow you to evaluate a stored reference value or values in the
meter by comparing “CMP” or in relation to “REL” or as a
percentage “%”.
3. REC Push-button: Function allows you to record minimum,
maximum and average values for a series of measurements on
the same function and range.
4. RANGE Push-button: Puts the meter in manual range mode.
holding it down for two seconds exits this mode.
5. Hold Push-buttons: Freezes the reading on the LCD for all
functions and ranges.
6. ON/OFF Push-buttons: Turns the meter on and off. If the rotary
switch or a push-button is not activated within 30 minutes, the
meter automatically turns itself off.
7. A Input Jack: The red test lead is plugged into this jack for
measuring current on the 10 AC or DC amp functions.
8. mAµA Input Jack: The red test lead is plugged into this jack for
measuring current on the 4m and 400m AC or DC amp functions.
9. VΩHz Input Jack: The red test lead is plugged into this jack for
all AC V, DC V, Ohm, Continuity Buzzer, and Diode test functions.
10. COM Input Jack: The black test lead is plugged into this jack for
all measurements except temperature.
