4. CONSIDERATION OF MEASUREMENT (1) This C METER is intended for measuring the capacitance value of a capacitor. It is not intended for determining the “Q” factor for above reactive components. Misleading readings may be obtained if the measurement of capacitance of a resistor is attempted. (2) When measuring components within circuit that circuit must be switched off and de-energized before connecting the test leads.
PAGE 6
NOTE: (a) If the capacitance value is unmarked, start with the 200pF range and keep increasing until the over-range indication goes off and a reading is obtained. (b) A shorted capacitor will read over-range on all ranges. A capacitance with low voltage leakage will read over range, or a much higher value than normal. An open capacitor will read zero on all ranges (possibly a few pF on 200pF range, due to stray capacitance of the instrument).

6. MAINTENANCE 1) 9-Volt battery replacement a. Ensure the instrument is not connected to any external circuit. Set the selector switch to OFF position and remove the test leads from terminals. b. Remove the screw on the bottom case and lift the bottom case. c. Remove the spent battery and replace it with a battery of the same type. 2) Fuse replacement a. Ensure the instrument is not connected to any external circuit. Set the selector switch to OFF position and remove the test leads from terminals. b.

(3) 注意檢查（黑色和紅色）測試線，若損壞請更換. (4) 在佈滿灰塵的環境裡使用儀器應該定期進行清潔。 (5) 不要長期把儀器暴露在太陽下。 (6) 取出電池和打開保險絲蓋子之前，確認儀器任何連接或電源開關處於關閉位置。 (7) 所有的測量，應該連接到黑色測試線 “ - ”和紅色測試線 “+”。 5. 電容（C）測量步驟 (1) 將功能旋鈕轉到待測試電容的預期最大值選擇的範圍 (2) 電源會同步開啟。 (3) 檢查“0”位：如果測試的範圍是 200pF，2nF，20nF，應測試前檢查儀表顯示為“0”, 若有偏離請調整”ADJ〞調零旋鈕. (4) 當測試有極性電容器時，檢查其極性, 以對應測試插座 “+”端，”－” 端連接.

(e) 電容器，特別是電解電容，往往有廣泛的公差。不要感到驚訝，如果測量值大於標在電容器上的值，除非它是一個緊公差，不管如何測量，測量值很少大幅低於額定值。 (f) 如果更改測量檔位，測量顯示值將不同。電容器漏電壓也將隨檔位不同而變化, 在低檔測量位置.漏電電阻會變小。 6. 維修 1) 9 伏特的電池更換 a. 確認儀器不連接任何外部電路。確定儀器功能旋鈕轉向為 OFF 位置並且除去測試線。 b. 取下底蓋的螺絲與蓋子。 c. 取出電池並更換一個同類型的電池。 2) 保險絲更換 a. 確認儀器不連接任何外部電路。確定儀器功能旋鈕轉向為 OFF 位置並且除去測試線。 b. 取下底蓋的螺絲與蓋子。 c.
