4. INDUCTANCE (L) MEASURING PROCEDURES 1) Slide the " Power On/Off switch " (3-2, Fig. 1) to the " 1 " position. " 1 " = On " 0 " = Off 2) Slide the " L/C,R switch " ( 3-4, Fig. 1 ) to the " L/C " position. -
Page 8: Capacitance (C) Measuring Procedures
Consideration for internal circuit's stray inductance of 2 mH range, if intend to make the precision measurement, should short the input terminal first, record the display Then final true measurement value will be the " reading value " deduct above " internal circuit stray inductance " For example : If the stray inductance is -15 uH, then the real real value is the reading value plus 15 uH ( deduct -15 uH ). - Page 9 5) Read the display. The value indicated corresponds to the range selected. If the DISPLAY shows "1", it indicates an Out-of-Range measurement. In order to improve the resolution, Select the next higher range. NOTE: If the capacitance value is unmarked start 1) * with the Lower range ( 2 nF ) and keep increasing until a suitable reading is...

Page 10: Resitance (R) Measuring Procedures
A capacitor with low voltage leakage will read over range, or a much higher value than normal. An open circuit capacitor will read zero on all ranges (possibly a few pF on 2nF range, due to stray capacitance of the instrument). 5) Measurement of very low capacitance should be performed using extremely short leads in order to avoid introducing any stray capacitance. -

7. DIODE MEASUREMENT PROCEDURES PROCEDURE 1) Slide the " Power On/Off switch " (3-2, Fig. 1) to the " 1 " position. " 1 " = On " 0 " = Off 2) Slide the " L/C,R switch " ( 3-4, Fig. 1 ) to the " R " position. - Page 12 5) A. When connected with polarity as shown in Fig. 2, a forward current flow is established and the approx. DIODE forward voltage (VF) values in volt will display on the display reading. If the diode under test is defective, ".000" or near ".000"...
