Multiplier/Resistor Assembly Continuity and Resistance Check
(contd)
4. See Figure 5-2. Connect the shorting plug (4) to the
multiplier receptacle (3). Connect the megohmmeter probes to the
shorting plug ring-tong terminal and electrode. If the reading is infinite,
reverse the probes.
NOTE: This test can be made without a shorting plug. Connect all three
multiplier pins together before taking a reading with a megohmmeter.
Failure to do so could damage the multiplier. Contact your Nordson
representative for more information.

5. The megohmmeter should read between 208 and 312 megohms at
500 volts. If the reading is out of this range, unscrew the resistor probe
from the multiplier and check the resistor separately (refer to Resistor
Resistance Check ). If the resistor reading is within the range specified,
replace the multiplier.
6. See Figure 5-5. Check for continuity between the bottom pin (5 Vdc
feedback) in the multiplier receptacle and the heatsink.
