*1 The indication accuracy of the K1, T, and N thermocouples at a temperature of -100°Corlessis±2°C ±1 digit maximum.
The indication accuracy of the U, L1 and L2 thermocouples at any temperature is ±2°C ±1 digit maximum.
The indication accuracy of the B thermocouple at a temperature of 400°Corlessisunrestricted.
The indication accuracy of the R and S thermocouples at a temperature of 200°Corlessis±3°C ±1 digit maximum.
The indication accuracy of the W thermocouple is ±1 digit max. of whichever is the greater of ±0.3% or ±3°Coftheindi-
cated value.
The indication accuracy of the PLII thermocouple is ±1 digit max. of whichever is the greater of ±0.3% or ±2°Cofthe
indicated value.

F Heater Burnout Alarm
Max. heater current Single-phase 50 A V AC (see note 1)
Heater current value display accuracy 5%FS 1 digit max.
Heater burnout alarm setting range 0.1 to 49.9 A (in units of 0.1 A) see note 2)
Min. detection ON time 190 ms (see note 3)
Note: 1. Use the K2CU-FVVA-VGS (with gate input terminals) for the detection of three-phase heater burnout.
2. The heater burnout alarm is always O FF if the alarm is set t o 0.0A and always ON if the alarm is set to 50.0A.
3. No heater burnout detection or heater current value measurement is possible if the control output (heat) is ON for
less than 190ms.
