1. A digital multimeter, comprising:
- a measurement component for receiving measurement data corresponding to one or more physical or electrical parameters;
a user interface for receiving user input to place the digital multimeter in a recording mode;
a processor component for receiving user input to program at least one of an upper recording threshold and a lower recording threshold in the recording mode; and
a memory component for storing measurement data captured by the digital multimeter, whereinat least one of a first plurality of measurements greater than the upper recording threshold or a second plurality of detected measurements less than the lower recording threshold over a period of time are automatically and successively recorded;
in a sequence of measurements that are either above the upper recording threshold or below the lower recording threshold.

Abstract
A digital multimeter automatically records measurements of electrical or physical parameters. The multimeter may record the measurements based on events such as the passage of time, fluctuations or deviations in the measurements, or user inputs. In some examples, the digital multimeter operates at a reduced power setting during automatic recording operations.

17. A method of operating a digital multimeter, the method comprising:
-
receiving measurement data corresponding to one or more physical or electrical parameters; receiving a user-input for placing the digital multimeter in a recording mode; receiving user input to program at least one of an upper recording threshold and a lower recording threshold in the recording mode; and wherein, once the digital multimeter is in recording mode; automatically and successively recording at least one of a first plurality of individual measurements having a value greater than the upper recording threshold or a second plurality of individual measurements having a value lesser than the lower recording threshold, wherein the recording includes a sequence of measurements that are either above the upper recording threshold or below the lower recording threshold. - View Dependent Claims (18, 19, 20, 21, 22, 23)
