Title: +038=370.101-OE002T_02-Multical 801 Energimåler Kamstrup - Teknisk beskrivelse.pdf
During test, the calculator is supplied by the meter’s main supply. The enclosed external mains adapter powers the verification PCB with 12 VDC. The microprocessor simulates volume based on pulse frequency and the number of pulses per test point selected in the computer program. Temperature simulation is obtained by means of fixed precision resistors, which are automatically changed via relays controlled by the microprocessor.After the test, the computer reads the registers in the calculator and compares the values to the calculated values.The calibration result in percentage for each test point can be stored in the computer under the serial number of the tested MULTICAL 801 to be printed out later on a test certificate.Verification data
