※“S” represents SSR drive output support models which SSRP function (standard ON/OFF control, cycle control, phase control) are available. “C” represents selectable current and SSR drive output support models.
※Select "R" or "C" type in case of using heating&cooling control and "N" type in case of using standard control.
※CT input of TK4N is available only for the standard model which has alarm output 1.
※Display accuracy:
◎At room temperature (23℃±5℃)
• Thermocouple K, J, T, N, E type, below -100℃/Thermocouple L, U, PLⅡ type, RTD Cu50Ω, DPt50Ω: (PV ±0.3% or ±2℃, select the higher one) ±1-digit
• Thermocouple C, G, R, S type, below 200℃: (PV ±0.3% or ±3℃, select the higher one) ±1-digit
• Thermocouple B type, below 400℃: there is no accuracy standards.
◎Out of room temperature range
• RTD Cu50Ω, DPt50Ω: (PV ±0.5% or ±3℃, select the higher one) ±1-digit
• Thermocouple R, S, B, C, G type: (PV ±0.5% or ±5℃, select the higher one) ±1-digit
• Others, Below -100℃: within ±5℃
In case of TK4SP Series, ±1℃ will be added to the degree standard.
