Memory Key
Each press of this key saves the measured data, along with 3 other monitoring items: the name of the object being measured, operator’s name, and date and time of measurement.

Selection of Registered Tag Name
Select from the list of up to 50 registered tag names (objects to be measured).

Input Selection Key

Collector/Logging Mode Selector Key
Switches between the collector mode (saves measured data when necessary) and logging mode (saves measured data continuously).

Measuring interval: 1 second to 24 hours (Under simultaneous 2-channel measurement with the TM20, 2 seconds is the minimum.) Start-of-measurement time: timer can be set.

User-friendly FUNC Key
You can select setup items in the same way as you choose options from the built-in menu of a cellular phone.

Selection of Operator Name
With the (1) key, you can recall a list of up to 10 operator names and can also change any of these names.

Record-keeping On Measurement Failure Handling
By pre-registering a list of up to 32 comments on how to handle particular measurement failures, you can keep records of how the measurement failure was dealt with by selecting the desired comment from the list using the (4) key. (The TM10 supports this feature with TM10 Version 1.10 when used with application software version 1.30 or later.)

Setup Keys
Register tag names, set alarm points, and define measuring conditions, such as the measuring interval for the logging mode. These setting tasks can also be carried out from a PC.

Digital Input Terminal
For connecting to an optional non-contact probe.

RS-232C I/O Terminals
Used to exchange data with a PC or send data to a dedicated printer.

①	External probe connection jack (channel A) Used to connect a needle-type standard probe, a needle-type high-speed probe, or other probes.	⑨	[▼] [▲] key Used to select an appropriate tag, log, or function.
②	Radiation temperature probe connection jack (channel D) Used to connect a radiation thermometer.	⑩	[LOGGING] key Used to switch between the collector and logging functions. Also used to modify alphanumeric characters from uppercase to lowercase.
③	RS-232C communication connection terminal Used to output data from this instrument to a personal computer or printer.	⑪	[POWER] key Used to turn the power supply on and off.
④	Built-in sensor (channel C) Used to measure the external temperature.	⑫	[Set] key Used to make the setup contents valid for operation.
⑤	Display (LCD) Displays Thermo-Collector conditions, various setup information, measurement temperature, etc.	⑬	[Func] key Used to set up the selected function. Also used to delete the measurement data.
⑥	[CH] key Used to switch the current input channel. Available input channels include channel A (for probes), channel C (for the built-in sensor), and channel D (for the radiation temperature probe).	⑭	[1],...,[9], and [0] keys Used to enter alphabets and numbers. The [0] key is also used for switching the unit of temperature display. If, for example, this [0] key is pressed in the Home screen, the unit is switched to “°F”. Another pressing of the same key will restore the unit to “°C”.
⑦	[ESC] key Used to cancel the previous operation and return to the previous screen.	⑮	[<] and [>] keys Used to retrieve the logged tag data or log data, or to select the character input position.
