❐MAIN FEATURES AND FUNCTIONS
This product is intended to record the industrial quantities such as temperature, etc. on 180 mm-width chart paper. For the dot-printing
type, up to 12-channel recording and for pen type, up to 3-channel continuous recording is available.
(1) Features
Main features are as follows:
•Recording operation can be started without operations for setting or others depending on specified input conditions.
•Standard input type can be specified among 31 types (18 types for thermocouple, 6 types for DC voltage, and 7 types for resistance
thermometer).
The input type and scale width can be specified from 10 ranges of DC voltage, 26 ranges of thermocouple, and 6 ranges of
resistance thermometer other than standard input types.
•Universal power supply input is available. The measuring power voltage range is 100 to 240 VAC and 50 Hz/60 Hz.
•Any operations can be executed at the front. For inkpad replacement of the dot-printing type, pull out the inner unit to the position of
the middle stopper (it cannot be pulled out after the middle stopper position) then perform the replacement. For cartridge pen
replacement of the pen type, pulling out the inner unit is unnecessary.
(2) Functions
Main functions are as follows:

indicate input specifications.
Input codes include particular codes for the factory administration
(Refer to 11.3 Accuracy Rating List. (1) Standard Input).
Non-standard input may be indicated with “XX”.
*The column other than input codes is blanked out.
(2) Information
1) Chart Paper Attached
The chart paper No. EH01001 (0 to 100) is attached for operation.
For standard input specification, specified chart paper is available.
(Refer to 11.3 Accuracy Rating List (1) Standard Input Chart No)
Example for chart paper corresponding to various scales is shown
