    71M6515H Demo Board User’s Manual CALIBRATING THE DEMO METER The general calibration procedure is as follows: Obtain the deviation from ideal accuracy using a meter calibration system (see section 2.1). Calculate the calibration values using the error terms obtained in step 1 (see section 2.1).

  • Page 27: Application Information

    It is also very important that the calibration system, just like the hookup of a real meter, applies voltage constantly while varying the current. For the calibration of the 71M6515H it is essential that voltage is applied at least a few seconds before the measurement is started, i.e. before current is applied. This is necessary because: •...

    The oscillator of the 71M6515H drives a standard 32.768kHz watch crystal (see Figure 2-8). Crystals of this type are accurate and do not require a high current oscillator circuit. The oscillator in the 71M6515H has been designed specifically to handle watch crystals and is compatible with their high impedance and limited power handling capability.
