The Keysight U1177A is the key enabling piece of wireless remote connectivity for Keysight handheld digital multimeters (DMMs) and U1210 Series clamp meters. Attach the U1177A to the IR port of a Keysight handheld DMM* to establish a Bluetooth® wireless connection with an Android device (whether a smartphone or tablet).

Keysight Mobile Meter is a free Android-based application that allows an Android device to connect, control, and measure with up to three handheld DMMs. Users can extend their reach and be in more than one place at the same time.

Keysight Mobile Logger is another free Android-based application that allows an Android device to log measurements and plot trending graphs from as many as three handheld DMMs. These data and graphs provide further analysis to identify intermittent behavior and detect drifts.
