If any of the items are damaged or missing, return the complete package to the place of purchase for an exchange. INTRODUCTION Multimeter AM-250 can be used to measure voltage, resistance, capacitance, frequency, current and temperature; It is an electronic measuring instrument that combines several measurement functions in one unit. AM-250 multimeter...
Note: 1) AC 400.0mV range selection is by RANGE button manually, and is specified from AC 10mV and up. 2) DC 400.0mV range is designed with 1000Me high input impedance for least current drain in measuring small signals, and can cope better with most commercially available voltage output transducers and adapters.
Caution � Using Resistance, Continuity, Diode or Capacitance function in a live circuit will produce false results and may damage the instrument. In many cases the suspected component must be disconnected from the circuit to obtain an accurate measurement reading. Diode test,Capacitance functions Defaults at e.
Caution � Discharge capacitors before making any measurement. Large value capacitors should be discharged through an appropriate resistance load µA, mA, and A Current functions Default at DC. Press SELECT button momentarily to select AC. Caution � When measuring a 3-phase system, special attention should be taken to the phase-to-phase voltage which is significantly higher than the phase- to-earth voltage.
Press SELECT button momentarily to select degree F (Fahrenheit). You can also use a plug adapter (Optional purchase) with banana pins to type-K socket to adapt other type-K standard mini plug temperature probes (refer to www. amprobe.com). Relative zero mode...
Manual or Auto-ranging Press the RANGE button momentarily to select manual-ranging mode, and the meter will remain in the range it was in, the LCD symbol turns off. Press the button momentarily again to step through the ranges. Press and hold the button for 1 second or more to resume auto-ranging mode.

MAINTENANCE AND REPAIR If there appears to be a malfunction during the operation of the meter, the following steps should be performed in order to isolate the cause of the problem. 1.Check the battery. Replace the battery immediately when the “...
Battery replacement: Loosen the 2 screws from the battery access door of the case bottom. Lift the battery access door and thus the battery compartment up. Replace the battery. Re-fasten the screws. Fuse replacement: Loosen the 4 screws from the case bottom. Lift the end of the case bottom nearest the input jacks until it unsnaps from the case top.
