The TM20 offers excellent data management functions:
- Collect up to 5000 data items with time-stamp, tag name and inspector name.
- Save 2 weeks continuous data logging with 1 minute interval (up to 20000 data items, measuring interval is 1sec. to 24 hours.).
- Information on when, by whom and what is measured is saved along with the data.

- 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).
When used in the collector mode only, saves up to 5000 data items.
When used in the logging mode only, saves up to 20000 data items.
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.
