Caution
1.
The areas shaded or marked with Z\ on the schematic diagram and parts list designate
components which have special characteristics important for safety. Replace these parts only with parts
identical to those in the original circuit or specified in the parts list. Before replacing any of these
components carefully read the "Product Safety Notice."
2.
When taking measurements, pay special attention to the following:
1) Do not use your instrument between primary ground (symbol wo) and secondary circuit.
2) Do not use your instrument between secondary ground (symbol 7/7) and primary circuit.
Warning
_ This equipment contains safety critical components. All parts shown with the Z\ mark on the schematic
are safety critical.
Replace safety critical parts with only manufacturers recommended parts. See parts list for exact
replacements.
Note
1.
Resistance is shown in OHM. K = 1000 M = 1,000,000 and the rated power of resistors not noted in
schematic diagram is 1/4W.
2.
Capacitance is shown in pF. Capacitances not otherwise noted are shown in pF (1pF = 1,000,000 pF).
Rated voltage of condensers not otherwise noted in schematic diagram is 50 V.
