- Page 4 On page 6-14, replace Step 4 with: Set the multifunction calibrator to the same voltage as the voltage on the mains input of the Calibrator (5320A). 115 V or 230 V for example. Set the multifunction calibrator frequency to 55 Hz.
- Page 5 Ground Bond Resistance or Loop/Line Impedance functions are used daily. If these functions are used less often, relay cleaning should be performed every 90 days. If the 5320A has been powered off for more than 30 days, the relay cleaning procedure should be performed before usage.
- Page 6 2. Navigate to the Relay cleaning procedure as outlined above. Do not start the procedure. 3. Set the external power supply to 20 V and connect as shown to the PE and N terminals of the 5320A. It is best to use an external analog (linear) supply source. If a switching dc supply source is used, two resistors and one capacitor should be inserted between the power supply output and the 5320A input as shown in the diagram.
- Page 7 Manual Supplement 5320A Users Note For units with serial number lower than xx548xxxx, do not run the cleaning procedure without connecting the external power supply. When the cleaning procedure is performed without connecting the external power supply, the relay contact resistance may become even worse.
