Model: VMS400

Special Features:

Detector module and printer/controller, housed in briefcase, identity and quantity the following ac and dc voltage disturbances: low and high voltages, sags and surges, impulses, common mode noise, power outage, high and low frequency, phase angle unbalance, phase voltage unbalance and external events

Properties:

An item that accepts fixed voltages from test points in another component or set, and displays them in such a manner that deviation from a predetermined voltage value is readily apparent. The display is in terms of "good" and "bad" and is not in terms of voltage values. For items that display the same or similar information that is derived from a radio frequency signal input, see monitor, error voltage. For items that indicate voltage values in either scaler or digital form, see voltmeter. See also indicator (as modified).
