The BN-45 is the big brother to the BM-35 series meters, with a 4 1/2 digit voltmeter in a compact 96x24mm case with non-isolated 5VDC power. The case has a short depth of just 2.83 inches (72mm) behind the panel. The meter has three user-selectable ranges of 2V, 20V and 200V. The BN-45 may also be calibrated at the factory for these ranges or specially scaled for other ranges (see Ordering Infor- mation below). Provision to offset the zero is also available as an option for 4-20mA signals. The display is shipped standard with red LEDs, but green LEDs or super bright LEDs for high ambient light environments are also offered. Display Segments Test, Display Blank and Hold Reading are standard features.
