The fine charge resistors should match the input resistance Ri of the current input amplifier. In ST2684/ST2684A 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 75 ST2684/A Operation Manual Chapter 6 Measurement Procedures and Examples Figure 6.5.2 Wiring of sorting machine The precharge stations are supplied from HV2. The return path of the charge current must be the HV2 return and each precharge station must have its own return wire.

Connecting ST2684/ST2684A series Insulation Resistance Tester When connecting the ST2684/ST2684A to the DUT, there are few issues to address to ensure safety, noise free measurement, and minimum disturbance of the surroundings and long term stability of the instrument. The general rule is to avoid electrical loops that can pick up magnetic noise fields (hum) and add self-inductance. - Page 77 ST2684/A Operation Manual Chapter 6 Measurement Procedures and Examples or unstable connection can lead to high-current flashes during the (attempted) charging of DUT. The best way to protect against flashovers is to place wire wound resistors as close as possible to the DUT. In this way the transients resulting from the flashovers are damped near the source.
- Page 78 After the measurement the capacity has to be discharged. In ST2684/2684A, 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.
