Operation 5.1 Power On 5.1.1 Plug 5V adapter, LC-100A can be powered by a mini USB interface or 5V power adapter with 5.5DC Socket.You can also power the instrument with 4 of AA Batteries. 5.1.2 Switch on. The meter will show the company name and product model. 5.1.3 Enter capacitor test status. 5.2 Test You should select the appropriate gear based on the approximate range of the device under test. Before the test, the display will be different when the test clips open or short. Test clips open Test clips short Capacitance (C) show Inductance (L) show MEASURE Cx 0.00pF MEASURE Lx OVER RANGE MEASURE Cx OVER RANGE MEASURE Lx 0.000uH Large inductance (Hi.L) Show MEASURE Hi.L OVER RANGE MEASURE Hi.L 0.000mH Large capacitance (Hi.C) Show MEASURE Hi.C 0.00uF MEASURE Hi.C 0.00uF 5-1 Each Gears open, shorted display status 5.3 Calibration If the meter test clips open, the capacitor value displayed is not zero, or short-circuit inductance value test instrument display is not 0, you can reset to "0" by ways of capacitance model and inductance model. 5.3.1 Capacitance model 5 LC-100A Meter Press red button as testing clips open, it will displays "CALCULATING...", keep pressing the button for one second, when the meter shows "CALCULATING...OK" , release the red button. Resetting to "0" is finished, and "0.00pF" is displayed, then capacitances can be measured. 5.3.2 Inductance model Press the red button when the test clips short,the meter will show "0.000uH" or "0.000mH", then inductances can be measured. 5.4 Measurement operation You should select the appropriate gear based on the approximate range of the device under test. After the boot, make sure all the buttons are in the bounce, the default program is small capacitor gear, you can directly measure capacitance in the 0.01pF ~ 10uF range. In the Hi.C gear, make sure the test capacitor is fully discharged, then pick the red test clip to the capacitor positive, the black one to the capacitor negative. The test result can be read from the display. It should be noted that when measuring a larger capacitance (10mF above), the test time will be more than 1 second, the greater the capacitance the longer the test time.100mF takes about 7-8 seconds. If the test result is not accurate enough, you can calibrate it as follows, Press red button as testing clips open , it will displays "CALCULATING...", keep pressing the button for one second, when the meter shows "CALCULATING...OK" , release the red button to complete the calibration process. 5.5 Check the Frequency If you want to see the current frequency of the device under test. Please press function button as results displayed, and corresponding frequency will be displayed. 6. Cautions 6.1 Please reset to "0" before testing a capacitance or an inductance, or errors may be appeared. Even if "0" displayed before measuring, resetting to "0" is 6 LC-100A Meter needed. 6.2 At the time of resetting to "0", when"CALCULATING...OK" appeared, please keep pressing for 2 to 3 seconds, and the parameter written to "<DATA SAVED>" will be prompted, then release. 6.3 Resetting to "0" is forbidden as components are being measured. If you do it, please shut down immediately and restart, then reset to "0". 6.4 The time of measuring a big capacitance (above 10mF) may be more than one second, and it needs seven to eight seconds to get the measured value of the capacitance (100mF). 6.5 Forbid to measure a capacitance which is not discharged, otherwise it may damage the mainframe. 7.
