Specifications: Material: ABS+Metal Size: 110X60X36mm/4.33X2.36X1.42 in Working voltage: AC90~260V Power consumption: less than 2W Measuring accuracy: 0.5%FS1 Measuring range: -40~110 Code Table: TY1: Relay 1 output alarm type 0: Upper limit alarm, temperature AL1, the relay is closed, (AL1-HY1), the relay is off. 1: Lower limit alarm, temperature AL1, the relay is closed, (AL1+HY2), the relay is off. 2: Upper and lower limit alarm. Temperature AL1, the relay is closed, HY1, the relay is closed. AL1: Relay 1 action value: -40.0~130.0 HY1: Relay 1 return difference: -40.0~130.0 TY2: Relay 2 output alarm type 0: Upper limit alarm, temperature AL2, the relay is closed, (AL2-HY2), the relay is off. 1: Lower limit alarm, temperature AL2, the relay is closed, (AL2+HY2), the relay is off. 2: Upper and lower limit alarm. Temperature AL2, the relay is closed, HY2, the relay is closed. AL2: Relay 2 action value: -40.0~130.0 HY2: Relay 2 return difference: -40.0~130.0 SEC: Relay action delay value: 0-999 seconds When the relay AL1 or AL2 reaches the operating conditions, it will delay the action for SEC seconds. When it is 0, there is no delay. LC: Temperature deviation correction value: -20.0~20.0 (display value = measurement value + LC) Note: Please allow 1-3cm error due to manual measurement. Please make sure you do not mind before purchase. Due to the difference between different monitors, the picture may not reflect the actual color of the item.
