GOLDCHAMP DT-4070L Capacitor Tester Multimeter Instruction Manual

INTRODUCTION

This instrument is a compact battery operated handheld with safety protector streamline 3 1/2 digital LCR multimeter designed for use by technicians servicemen students and hobbyists who required an instrument that is accurate reliable and always ready for use. The Dual-slope-A/D converter uses C-MOS technology for auto-zeroing polarity selection and over-range indication. Full overload protection is provided. It is powered by a standard 9V transistor radio type battery .please read this manual that describes various useful message before using the multimeter.

HOW TO USE THE MULTIMETER

PRELIMINARY NOTE

1. If the battery is weak. a “ ” sign will appear on display.
   The battery should be replaced.

2. The FUNCTION switch should be set to the range to be used before operation.

Resistance Measurement

1. Connect the BLACK test lead to the “COM” jack and the RED test lead to the “Ω” jack .
2. Set the FUNCTION switch to “OHM ” range to be used
3. Connect the test leads across the resistance under measurement.

Note:

1. If the resistance value being measured exceeds the maximum value of the range selected, an over-range indication will be displayed (“1 or -1”). Select a higher range .For resistance of approximately 1 Megohm and alove . the meter may take a few seconds to stabilize . This is normal for high resistance readings.
2. when the input is not connected , input is open circuit .the sign “1 or -1” will be displayed for the overrange condition . when checking in-circuit resistance, be sure the circuit under test has all power removed and that all capacitors are fully discharged.

Capacitance Measurement

1. Set the FUNCTION switch to “C” to be used.
2. Insert the capacitor under measurement into the two jacks “LC-” and “LC+ at the left on the front panel.

Note:

1. Capacitors should be discharged before being inserted into the test-jacks.
2. When testing large capacitance, note that there will be a certain time lag before the final indication.
3. Do not connect an external voltage or charged capacitor (especially larger capacitors) to measuring terminals.

Inductance Measurement

1. Set the FUNCTION switch to “L” to be used.
2. Insert the induct or under measurement into the two jacks “LC-” and “LC+ at the left on the front panel.

Transistor hFE Test

1. Set the FUNCTION switch the “hFE” range.
2. Determine whether the transistor is NPN or PNP and locate the Emitter. Base and collector leads. Insert the leads into the proper holes in the socker on the front panel.
3. The display will read the approximated hFE value at the test condition Base current 10uA , Vce 3V.

MAINTENANCE

1. The multimeter is a precision electronic device. Do not tamper with the circuity to avoid damage:
   A: Never connect a source of voltage under the condition of resistance measurement .
   B: Never operate the meter unless the cover is in place and fully closed .
   C: Battery replacement should be done after the test leads have been disconnected and POWER IS OFF.

2. turn off the power if the meter is not in use , removedthe battery if the meter will be free for long period

3. If a sign “ ” appear on the display, open thecompartment cover, remove the spent battery andreplace it with a battery of the same type.

4. Contact with the maintenance service center of ourcompany if you have trouble.

5. Please take out the battery when not using fora long time.
