3.when input exceeds upper limit of measuring range by 10%
1.wire breaking check of thermocouple input wiring,
replacement of thermocouple
2.check of resistance bulbA wiring, replacement of
resistance bulb
3.check of input voltage value and current value, input
transmitter and specification (matching of incoming
signal and meter specification)

Display accuracy : ±(0.25%FS+1digit)CJ errors not included, B thermo couple below 400℃ is not guaranteed.
Display accuracy during EMC examination is ±5%FS.
Accuracy maintenance range : 23±5℃
Display range : -10%-110% of measuring range, but Pt100's -200~600℃ is -240～680℃
Display resolution : Changes with measuring range and scaling.
Input scaling : Possible at the time of voltage input and current input -1999-9999 (spang 10 – 10000 count, decimal point position
no decimal point 0.1, 0.01, 0.001)
Setting
Setting system : By five front keys （ , , ）.
ＳＶSetting range : Same with measuring range
Setting lock : Communication and key seting (three levels), DI (one level)
Operations Level Lock Content
OFF No lock
1 Execution SV and a manual numerical change are possible. And change of a keylock level is possible.
2 Possible to change numerical value manually and keylock level.
Communication
＆
Key setting
3 Possible to change keylock level.
4 Only change of a keylock is possible It can be locked key
DI Setting Super Key Lock (Shift between screens prohibited. Fixed only to the basic screen.)
＊Regardless of the setting lock by communication & key setting, the key is always effective.
However, even key is not received when super keylock by DI is performed.
SV setting limiter ：Same with measuring range ( lower limit ＜ upper limit )
Unit setting ：Settable at the time of sensor input ℃,°F
Input
Multi input
Thermocouple ：500Ω or more, external resistance tolerance level 100Ωor less input resistance
Influence of lead-wire ：1.2μＶ／10Ω
Burnout ：Standard equipment (Up Scale only)
Measuring range ：Item 5-5. Refer to measuring range code table.
Compensation accuracy
of reference junction ：±１℃ (ambient temperature 18-28℃) At the time of vertical plural proximity attachment ±２℃
±２℃（ambient temperature 0-50℃） At the time of vertical plural proximity attachment ±３℃
