[. . . ] Before beginning all unknown measurements, set meter to highest possible range. Before breaking a circuit for testing, turn off the power to the circuit. When disconnecting from a circuit, disconnect the hot lead first, then the common lead. Disconnect the meter from the circuit before turning off any indicator, including motors, transformers, and solenoids. [. . . ] Plug the Black test lead into the COM port and the Red test lead into the port. Measure DC Voltage Input Impedance: 10M (over 1000M in 400mV range)

*This spec is not guaranteed. Plug the Black test lead into the COM port and the Red test lead into the VHz port. Turn the power off to the circuit or device that is to be measured and discharge all capacitors before attempting a measurement. Plug the Black test lead into the COM port and the Red test lead into the VHz port. For correct reading, ensure that the device being tested contains no voltage. Overload Protection: 600V Open Circuit Voltage: -1. 3V (approx. )

Turn off power to the device or circuit that is being tested and discharge all capacitors. Plug the Black test lead into the COM port and the Red test lead into the VHz port. Normally the forward voltage drop of a good silicone diode is shown between 400V and 0. 9V. If the diode under test is defective, "000" (short circuit) or "OL" (non-conductive) is displayed. Overload Protection: 600V max
* In these two ranges the reading may be rolling within specification To Measure Capacitance: 1. Turn the power off to the circuit or device that is to be measured and discharge all capacitors before attempting a measurement. Plug the Black test lead into the COM port and the Red test lead into the VHz port. Measure Capacitance In order to ensure the best accuracy in measurement of low capacitance, open the test leads before measurement and memorize the test probe capacitance. It is necessary to subtract the capacitance of the test probes themselves, or use the relative mode to compensate for the test leads. Overload Protection: 600V

To Verify Continuity: 1. [. . . ] This warranty does not apply to defects resulting from abuse, neglect, accident, unauthorized repair, alteration, or unreasonable use of the instrument.
Fuse Replacement 1. Remove the test leads from the front terminals and turn the meter off. Remove the two screws connecting the top and bottom cases of the meter. Remove the defective fuse by gently prying one end of the fuse loose and sliding the fuse out of the fuse holder. [. . . ]
