WARNINGS

To ensure safe operation and service of the tester, follow these instructions.

Failure to observe these warnings can result in severe injury or death.

•

Follow the manufacturer’s maintenance procedures when

servicing equipment.

•

Place ONLY thermocouples (type K, J, T, or E) in the thermocouple

ports.

•

Make sure your meter is set for the proper thermocouple type.

•

Be sure the thermocouple you use can withstand the temperature

extreme it may be exposed to in your service task.

•

Properly maintain your thermometer and calibrate it regularly.

•

Do not use if the thermometer has cracks or any other damage to

the case.

•

Disconnect thermocouple before replacing batteries or opening

case.

•

Replace batteries when low battery indicator appears on the

screen. Low batteries can aversely affect thermometer accuracy.

•

Do not apply voltage to thermocouples. There should be no more

than 1V between any two thermocouples, and no more than 30V

between any thermocouple and earth ground.

The minimum (MIN) or average (AVG) reading can be

displayed in the similar way.

•

Press “

MAX/MIN

” for more than 1 second or “

” button

for more than 1 second to exit MIN/MAX mode.

5. Using the Offset to Compensate for Probe Errors

•

Use the offset option in “

SETUP

” to adjust temperature

readings to compensate for the errors of a specified

thermocouple.

•

Plug the thermocouple into the input terminal.

•

Place the thermocouple in a known stable temperature

environment (such as an ice bath or a dry well calibrator).

•

Allow the readings to stabilize.

•

In “

SETUP

”, change the offset until the primary display

reading matches the calibration temperature, see:

Set Up Instructions

section,

Set Up Instructions section,Set Up Instructions

I : Setting Temperature Offset

6. Using Memory

•

During logging session, the thermometer stores logged

readings in its memory. At the end of the logging session you

can view the logged readings on the display. You can also

transfer the logged readings to a PC running the optional

software, which displays the readings on an online form,

which can be printed or stored for later use.

7. Initial Conditions and Data Entries

•

Logged readings include initial conditions and data entries.

The initial conditions are the thermocouple type and the

offsets for each thermocouple input. You can only view initial

conditions using the included software.

•

The data entries are a time stamp and the T1, T2, T3, T4 T1-T2

and T3-T4 reading. You can view these values by pressing

“

RECALL (SETUP)

” momentarily or using the optional software.

The thermometer has 9,999 memory locations. The thermometer

stores 9,999 sets of temperature readings and one set of initial

conditions when logging continuously. It stores 9,999 sets

of temperature readings and initial conditions when logging

individual points manually.

8. Starting and Stopping Logging

•

Memory clear, and PC communications are inaccessible during

logging. Recall function is enabled during logging.

•

Set the time and the logging interval, see:

Set Up Instructions

sections,

E: Time

, and

Change Logging Interval

Change Logging Interval.Change Logging Interval

•

Press “

LOGGING (CLEAR)

” momentarily to start logging. The

display shows “

LOG

“.

•

Press “

LOGGING (CLEAR)

” momentarily again to stop logging.

9. Clearing Memory

•

When memory is full, “

FULL

“ appears in the secondary

display and logging stops. You can clear memory in normal or

MAX/MIN mode.

•

Press “

LOGGING (CLEAR)

” for more than 1 second to display

“

” in the RECALL mode.

•

Press “

LOGGING (CLEAR)

” for more than 1 second again to

delete all logged readings from memory.

•

Press “

EXIT

” momentarily or turn off the thermometer to stop

clearing memory.

10. Viewing Logged Readings

•

Press “

RECALL

” momentarily to display the last logged

reading. If there is no logged readings, “

” appears in

the secondary display, and the thermometer returns to the

previous mode.

•

Press and hold“

”

or “

”

to scroll through the logged

readings. The display shows each logged reading and its time

stamp, which is displayed 2 seconds after its memory location

appeared in the secondary display.

•

Press “

MAX/MIN

” momentarily to step through the minimum,

maximum, average, and currently logged reading.

•

Press “

T1/T2 T3/T4 (T1-T2, T3-T4)

” momentarily to display

the logged readings you want to view. Press “

T1/T2 T3/T4

(T1-T2, T3-T4)

” for more than 1 second to display differential

values between the logged readings you want to view.

•

Press “

RECALL

” momentarily to stop viewing logged readings.

•

NOTE:

maximum of all logging sessions in memory.

11. USB Port / External Power

•

This thermometer is equipped with an USB interface port and

cable. Optional Windows® compatible software is available

for download at www.kleintools.com. This kit is required to

connect the thermometer to a PC.

•

The kit allows you to transfer the current data measured and

the contents of the thermometer’s memory to a PC. Refer to

the “HELP” menu in the software for further details.

•

The DTL304 can be powered through the USB cable or

included AC adapter. This allows long term monitoring or

logging without consuming battery power

•
