Introduction
Thank you for purchasing your REED R2815 Temperature Calibrator.
Please read the following instructions carefully before using your
instrument. By following the steps outlined in this manual your meter will
provide years of reliable service.
Product Quality
This product has been manufactured to meet the stated product
specications. If a certicate of calibration is required please contact the
nearest authorized REED distributor or authorized Service Center. Please
note an additional fee for this service will apply.
Safety
Never attempt to repair or modify your instrument. Dismantling your
product, other than to replace batteries, may cause damage that will not
be covered under the manufacturer's warranty. Servicing should only
be provided by an authorized service center. To avoid injury to the user
or damage to the instrument, please read the safety information below
before initial use:
• Do not operate the instrument around ammable or explosive gas,
vapor or dust.
• Never apply more than 30V between any two terminals, or between any
terminal and ground terminal.
Note: For optimal accuracy, allow the instrument to warm up 5 minutes
before operating. If the automatic reference-junction temperature
compensation of the instrument deviates from its designed accuracy,
contact an Authorized REED Service Center.

Operating Instructions
Power ON/OFF
Press the Power button to turn the instrument on. To turn the instrument
off, press and hold the Power button.
Auto Power-Off
As a default, the instrument will automatically turn off after 5 minutes of
inactivity. To turn off this feature, refer to the "Enabling/Disabling Auto
Power OFF" section of this manual for additional details.
Backlight
Press the Backlight button to turn the LCD Backlight on or off.
Note: The backlight automatically turns off after approximately 60
seconds by default. To turn it back on, press the Backlight button. The
backlight illumination duration can be adjusted in the factory settings.
For more information, refer to the "Setting Backlight Time" section of this
manual for additional details.

Output Function
The output terminal of the instrument can produce DC voltages or can
simulate thermocouple temperature set by the user.
To avoid electric shock, ensure that the voltage applied between the
calibrator terminals or between any terminal and ground does not
exceed the rated voltage specied for the calibrator. Do not use the
calibrator in situations where the terminal-to-ground voltage exceeds
30V peak.
Connecting Leads to Output Terminals
Connection method for all outputs:
1. Connect the black lead to the COM terminal and the red lead to the
V/Ω terminal of the output.
2. Attach the opposite ends of the leads to the input terminals of the
controlled device, ensuring that the terminal polarities are correct.

Outputting DC Voltage
1. Press the MEASURE/SOURCE button to switch to the output mode.
The SOURCE indicator will illuminate on the display. By default, the
calibrator will be in DC voltage mode with an initial measurement
range of 100mV. The "mV" symbol on the right side of the main
display will light up.
2. Press the RANGE button to select the desired measurement range
(options: 100mV, 1V).
3. Set the output value using the output setting buttons:
• Change the digit to be adjusted using the
• Adjust the value using the buttons.

Analog Output Resistance
1. Press the FUNC button to switch to the analog resistance function.
The "Ω" symbol on the right side of the main display will light up,
indicating resistance mode.
2. Press the RANGE button to select the desired measurement range
(400Ω / 4KΩ).
Note: For the 400Ω range, two excitation currents are available: 1mA
and 0.1mA. You can manually switch between them to improve accuracy
based on your needs.
To set the excitation current:
• Press the CONFIG button to enter the excitation current setting
menu. "OHM.IS" will appear in the secondary display area at the
lower right corner.
• The main display area will show "I-H" for 1mA or "I-L" for 0.1mA.
• Use the

• Press CONFIG button to exit the setting menu.
3. Set the output value using the output setting buttons:
• Change the digit to be adjusted using the

Note: If the excitation current does not match the selected range (400Ω), the
excitation current indicator on the right side of the display will flash. In this case,
return to the setting interface to adjust the excitation current appropriately.

Analog Output Thermocouple
1.
Press the FUNC button to switch to the thermocouple (TC) function.
The "TC" indicator in the upper right corner of the display will light up.
2. Press the RANGE button to select the desired thermocouple type (R,
S, K, E, J, T, N, B, A, C, D).
3. If cold junction compensation is required, press RJ-ON to activate
the cold junction compensation function. If not, skip this step.

There are two types of cold junction compensation:
Automatic: The instrument uses its internal temperature sensor to detect
the ambient temperature automatically.
Manual: The user sets the cold junction compensation temperature
manually.
To set cold junction compensation:
• Press the CONFIG button to enter the cold junction compensation
settings menu. "RJST" will appear in the secondary display area at
the lower right corner.

• Press the ZERO button to perform a reset operation in any
measurement range of the DC voltage, resistance, thermocouple, or
thermal resistance output functions.
•
This action will reset the output setting value to the default initial value,
providing a convenient way for users to quickly return to the starting point.
Measurement Mode
Warning: When using the calibrator in measurement mode, ensure
that all connections are made with the proper leads. The maximum
allowable voltage between any input terminal and ground is 60V peak.
Exceeding this limit may result in electric shock. Never apply a voltage
higher than this maximum to the terminal or ground.
If the measured value exceeds the allowable measurement range, the
"OL" (Overload) symbol will appear in the main display area, indicating
that the input is out of range.
Connecting Leads to Input Terminals
Connection Method for DC Voltage, Thermocouple, Thermal
Resistance, and Resistance (2W) Measurement:
1. Connect the black lead to the COM terminal of the input.
2. Connect the red lead to the VΩ terminal of the input.
3. Attach the other ends of the two leads to the measurement terminals
of the device under test.
4. Ensure that the terminal polarity is correct to ensure
accurate measurements.
