• Sampling rate: 1 S/s
• Thermocouple accuracy is not included.
• Cold junction temperature shall be input by TEMP/SENSOR menu and does not include its
error.
• In calculational guarantee temperature 0°C to 18°C and 28°C to 50°C, ±0.1°C/°C is added to
all thermocouples.
• It is outside the accuracy guarantee though temperatures that are lower than -200°C might be
displayed as measurements.
• Standard heat electromotive force depends on line graph approximate calculation by JIS C
1602.
• This instrument does not support internal reference junction compensation. Set the reference
junction compensation temperature manually (see section 4.3.9 in the IM DM7560-01EN).
Internal reference junction compensation: A function that measures internally the input
terminal temperature and compensates the temperature at the measurement point.
