NOTE ON USING CIRCUIT DIAGRAMS
1.SAFETY
The components identified by the symbol and shading are critical for safety. For continued safety replace safety ciritical components only with manufactures recommended parts. Type No indication MM PP MPP MF TF BP TAN (3)Coils No unit Others : Original setting position when shipped : DC 20kΩ/V :H :V : Othters (5)Voltage values 20µs / div 5ms / div Sweeping time is specified (4)Power Supply : B1 : 9V Respective voltage values are indicated (5)Test point : Test point (6)Connecting method : Connector : Wrapping or soldering : Only test point display : B2 (12V) : 5V : [µH] : As specified : Ceramic capacitor : Metalized mylar capacitor : Polypropylene capacitor : Metalized polypropylene capacitor : Metalized film capacitor : Thin film capacitor : Bipolar electrolytic capacitor : Tantalum capacitor
2.SPECIFIED VOLTAGE AND WAVEFORM VALUES
The voltage and waveform values have been measured under the following conditions. (1)Input signal (2)Setting positions of each knob/button and variable resistor (3)Internal resistance of tester (4)Oscilloscope sweeping time : Colour bar signal
: All DC voltage values
Since the voltage values of signal circuit vary to some extent according to adjustments, use them as reference values.
3.INDICATION OF PARTS SYMBOL [EXAMPLE]
In the PW board : R209 R209 (7)Ground symbol : LIVE side ground : ISOLATED(NEUTRAL) side ground : [Ω] : [kΩ] : [MΩ] : EARTH ground : DIGITAL ground : Receptacle
4.INDICATIONS ON THE CIRCUIT DIAGRAM
(1)Resistors Resistance value No unit K M
Rated allowable
