DC Voltage, AC Voltage, Hz Frequency functions
Inputs are made through the test leads terminals. Slide-switch on defaults at DC voltage. Press
SELECT button momentarily to select AC voltage.
Press the Hz push-button momentarily to activate Hz Frequency function in the following slide-
switch functions:
BM111 & BM112:
DCV & ACV via the test leads; ACA via the clamp jaw
BM125:
DCV, ACV, DC

high input impedance for least current drain
in measuring small signals, and can cope better with most commercially available voltage output
transducers/adapters. The non-zero display reading is normal when the meter inputs are open
circuit, which will not affect actual measurement accuracy. The meter will show close to zero
reading when the inputs are shorted. Open input is actually a floating condition, which is not a
zero-volt-input condition.
Note: Hz input sensitivity varies automatically with function range selected while activating the
Hz function. Lowest range has the highest sensitivity, and the highest range has the lowest
