1. temperature and DC0-10Vvoltage computing relationship

  The product comes standard with 0~50℃/-20~80℃/-40~60℃ multi-range. The default range is 0~50℃. Users can modify the range by dialing the switch. For example, the range is 0~50℃, the analog output is 0~10V DC0-10Vvoltage signal, temperature and DC0-10Vvoltage The calculation relationship is as shown in the formula: C = (A2-A1) * (X-B1) / (B2-B1) + A1, where A2 is temperature range upper limit, A1 is the lower limit of the range, B2 is DC0-10Vvoltage output range upper limit, B1 is the lower limit, X is the currently read temperature value, and C is the calculated DC0-10Vvoltage value. The list of commonly used values is as follows:
DC0-10Vvoltage(V)temperatureValue (℃) Calculation Process
00.0(50-0)*(0-0)÷(10-0)+0
15.0(50-0)*(1-0)÷(10-0)+0
210.0(50-0)*(2-0)÷(10-0)+0
315.0(50-0)*(3-0)÷(10-0)+0
420.0(50-0)*(4-0)÷(10-0)+0
525.0(50-0)*(5-0)÷(10-0)+0
630.0(50-0)*(6-0)÷(10-0)+0
735.0(50-0)*(7-0)÷(10-0)+0
840.0(50-0)*(8-0)÷(10-0)+0
945.0(50-0)*(9-0)÷(10-0)+0
1050.0(50-0)*(10-0)÷(10-0)+0
    As shown in the above formula, when measuring 5V, current DC0-10Vvoltage is 25℃。

2. humidity and DC0-10Vvoltage computing relationship

  For example, the range is 0~100%RH, the analog output is 0~10V DC0-10Vvoltage signal, humidity and DC0-10Vvoltage The calculation relationship is as shown in the formula: C = (A2-A1) * (X-B1) / (B2-B1) + A1, where A2 is humidity range upper limit, A1 is the lower limit of the range, B2 is DC0-10Vvoltage output range upper limit, B1 is the lower limit, X is the currently read humidity value, and C is the calculated DC0-10Vvoltage value. The list of commonly used values is as follows:
DC0-10Vvoltage(V)humidityValue (%RH) Calculation Process
00.0(100-0)*(0-0)÷(10-0)+0
110.0(100-0)*(1-0)÷(10-0)+0
220.0(100-0)*(2-0)÷(10-0)+0
330.0(100-0)*(3-0)÷(10-0)+0
440.0(100-0)*(4-0)÷(10-0)+0
550.0(100-0)*(5-0)÷(10-0)+0
660.0(100-0)*(6-0)÷(10-0)+0
770.0(100-0)*(7-0)÷(10-0)+0
880.0(100-0)*(8-0)÷(10-0)+0
990.0(100-0)*(9-0)÷(10-0)+0
10100.0(100-0)*(10-0)÷(10-0)+0
    As shown in the above formula, when measuring 5V, current DC0-10Vvoltage is 50%RH。
