    The latter makes it necessary to ensure that the capacitor is fully charged before measurement. This application note describes the fundamental of calculating the charge resistor values. General Fig. 6.5.1 shows the set-up for STB6684 with two HV supplys, one for precharging and one for fine charging and measurement. Current Measurement Board DB62X...
  • Page 86 The fine charge reistors should match the input resistance Ri of the current input amplifier. In STB6684/STB6684A IR tester, this resistor can be switched to either 10kΩ or 1MΩ. In figure 6.5.1 only two fine charge stations are shown, in many cases more than 10 stations are preferred.
  • Page 87 Wiring and installation in sorting machine When installing the STB6684/STB6684A IR tester and charge reistors in sorting machines, great care should be taken in the wiring. The general rule is to avoid electrical loops that can pick up magnetic noise fields (hum) and add self-indcutance.Also the effects of flash-overs (sparks) either within the DUT or...

    This also minimizes influence between measuring equipment, computers motor controls, etc. 6.6 Insulation resistance measurement Scope When measuring Insulation Resistance (IR) with STB6684/STB6684A, there are several issues to consider when comparing to resistance measurement with a common multimeter. This application note is intended to address some of these.

    STB6684/A Operation Manual Chapter 6 Measurement Procedures and Examples After the measurement the capacity has to be discharged. In STB6684/STB6684A, this is done by switching the output to a 2kΩ/5W wire wound resistor. The stored energy in a capacitor is calculated from: At 500V this limits the capacity that can be discharged by the internal resistor to 4mF.
