Amprobe AM-250 Digital-Multimeter - Manual (Page 9)

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. The non-
zero display reading is normal when the meter inputs are open circuit, which
will not affect actual measurement accuracy. Open input is actually a floating
condition, which is not a zero-volt-input condition. The meter will show zero
or close to zero reading when the inputs are shorted.

Resistance, and Continuity functions
Defaults at e. Press SELECT button momentarily to select Continuity
function which is convenient for checking wiring connections and operation of
switches. A continuous beep tone indicates a complete wire.
