Cooper-ATKINS TD2000 Heavy Duty Digital Thermometer Instruction Manual
INTRODUCTION
Cooper Instrument Corporation’s model TD2000 is a hand-held, dual-zone digital thermocouple thermometer which takes type K thermocouple probes. The temperature indication follows National Bureau of Standards and IEC 584 temperature/voltage tables for type K thermocouples.
SAFETY INFORMATION
It is recommended that you read the safety and operation instructions before
using the thermometer.
Warning: To avoid electrical shock, do not use this instrument when
voltages at the measurement surface exceed 24V AC or 60V DC. To avoid damage
or burns, do not take temperature measurements in microwave ovens.
Caution: Repeated sharp flexing can break the thermocouple leads. To
prolong lead life, avoid sharp bends in the leads, especially near the
connector.

OPERATING INSTRUCTIONS
Selecting the Temperature Scale
Readings are displayed in either degrees Fahrenheit (°F) or degrees Celsius
(°C). When the thermometer is turned on, it is set to the scale that was in
use when the thermometer was last turned off. To change the temperature scale,
press the F/C button.
Single Thermocouple Temperature Measurement
The thermometer displays the temperature of the thermocouple probe that is
connected to the selected input. Pressing the T1 button displays the
temperature of the thermocouple probe connected to the T1 input. Pressing the
T2 button displays the temperature of the thermocouple probe connected to the
T2 input. The display will indicate the mode by displaying T1 or T2 for the
active individual thermocouple probe.
Differential Temperature Measurement
The differential temperature measurement is selected by pressing the T1-T2
button. This causes the thermometer to display the temperature difference
between the two thermocouple probes (the temperature of thermocouple probe T1
minus the temperature of thermocouple probe T2). The display will indicate
T1-T2 when the differential mode is active.
HOLD Mode
To enter the DATA HOLD mode, press the HOLD button. The display will indicate
D-H when the mode is active. When the DATA HOLD mode is selected, the
thermometer holds the active input reading, T1, T2, or T1-T2, and stops all
further measurements. To cancel the DATA HOLD mode, press the HOLD button
again, and the thermometer will resume taking measurements.
MAX Mode
The MAX mode records and updates the maximum values for the selected input. To
select the MAX mode, first select the desired input (T1, T2, or T1-T2), then
press the MAX button. The display will indicate MAX when the mode is active.
To cancel the MAX mode, press the MAX button again.
In the MAX mode, to stop recording readings, press the HOLD button. Press the HOLD button again to resume recording.
OFFSET ADJUSTMENT
The OFFSET controls are located below the T1, T2 inputs, and are set at the
factory to allow for variations found in standard thermocouples. By adjusting
the OFFSET controls, you can optimize measurement accuracy for a particular
thermocouple, or pair of thermocouples, at a particular temperature.
Adjusting for T1 or T2 Measurements
- Connect the thermocouple probe to the T1 or T2 input connector and turn the thermometer ON (If using T2, press the T2 button).
- Place the thermometer in a known, stable environment at or near the temperature you wish to measure, and allow the reading to stabilize.
- Slowly adjust the OFFSET control that corresponds to the selected input (T1 or T2) so that the thermometer reading matches the temperature of the known environment. Leave sufficient time between adjustments to allow for measurement lag.
- The calibration of the thermometer-thermocouple probe combination is now optimized for measurement at the temperature measured in step 2.
Adjusting for T1-T2 Measurements
- Connect the thermocouple probes to the input connectors.
- Turn the thermometer ON and select T1-T2.
- Place both thermocouple probes in a stable temperature environment at or near the temperature you wish to measure, and allow the readings to stabilize.
- Slowly adjust either one, but not both, of the OFFSET controls until the thermometer reads zero. Leave sufficient time between adjustments to allow for measurement lag.
- The thermometer-thermocouple probe combination is now optimized for differential temperature measurement at the temperature used in step 3.
Resetting the OFFSET Controls
To return the OFFSET controls to their factory setting without having to
recalibrate the thermometer, perform the following procedure.
- Connect a thermocouple probe that is in good working order to the input that is to be adjusted.
- Place the thermocouple probe in an ice-water bath and allow the readings to stabilize.
- Slowly adjust the corresponding OFFSET control until the thermometer reads 32°F(0°C).
Battery Replacement
The appears on the LCD display when replacement is needed. To replace battery,
first disconnect the thermocouple probes from the thermometer before removing
the cover, then remove the three screws from the back of the thermometer and
lift off the front case. Remove the battery from the case bottom.
LIMITED WARRANTY
Any instrument which proves to be defective in material or workmanship within
one year of original purchase will be repaired or replaced without charge upon
receipt of the unit prepaid with proof of purchase. This Limited Warranty does
not cover damage in shipment or failure caused by tampering, obvious
carelessness, or abuse, and is the purchaser’s sole remedy.
