Introduction
The DT200 is a portable, battery operated temperature measuring
device. With its triple display screen, it allows you to measure two
inputs simultaneously, and record critical time stamped information.
Since the DT200 accepts type J, K, or T probes, you can use the probes
you have without changing your existing process technology. The backlit
display makes reading the LCD easy even in low light areas.
Features include
• -328 to 2498˚F (-200 to 1370˚C)
• Triple display
• Backlit display
• Dual input
• Differential temperature (∆T)
• Relative function displays temperature change
• Accepts K, J and T thermocouples
• Data hold
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.
Safety precautions
These are a few common safety practices for those working around
temperature critical environments:
• Follow the manufacturer’s maintenance procedures when
servicing equipment
• Place ONLY thermocouples (type K, J, or T) in the DT200
thermocouple ports
• Make sure your DT200 is set for the proper thermocouple type
you are using
• Be sure the thermocouple you use can withstand the temperature
extreme it may be exposed to in your service task
• Properly maintain your DT200 and calibrate it regularly
International Symbols
C o n t rols and Indicators
1. Power Switch: Powers instrument on and off.
2. Hold/Relative Switch: Freezes primary screen data or
establishes a relative zero for the primary screen information.
3. T1-T2 Switch: Toggles screen information from T1 (Primary)
and T2 (Secondary) to T2 Primary and T1 Secondary then to
T1-T2 (differential) on Primary and alternating T1 and T2
temperatures on Secondary.
4. Back Light Switch: Turns back light on. Automatically turns
off in 30 seconds.
5. K/J/T Thermocouples Select Switch: Selects proper input
reference for thermocouple in use (T1 and T2 must be the
same type).
6. ˚F/˚C Mode Select Switch: Toggles display data from degrees
Celsius to degrees Fahrenheit.
7. Record Mode Select Switch: Starts record mode (relative
clock), displays maximum and minimum temperatures
recorded on the Primary screen along with the relative time
they were recorded.
8. Thermocouple Ports: Positive and negative polarized plugs for
the thermocouple probes used (Blade type); T1 on the left, T2
on the right.
9. LCD Displays: Displays three screens of function and data
information.
10. Primary Data Screen: Displays T1, T2, or T1 minus T2
(temperature differential - TD) or a relative zero of T1, T2 or TD.
11. Secondary Data Screen: Displays time in hours and minutes
when Record is pressed and the relative time that NIM or MAX data
was recorded.
12. Relative Clock Screen: Displays time in hours and minutes when
record is pressed and the relative time that MIN or MAX data
was recorded.
