How to use?
1. temperature and DC0-10Vvoltage computing relationship
The product comes standard with 0~50°C/-20~80°C/-40~60°Cmulti-range. The default range is
0~50℃. Users can modify the range by dialing the switch. For example, the range is0~50℃, 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:
