# The innovative new meter offers wireless connectivity to your laptop or PC using a USB receiver with a range comparable to Bluetooth (10m/33 ft.). The EX540 transmits real-time data for monitoring, trending and analysis (using the included software) on one of two available frequencies (914 MHz). Now, electrical professionals can monitor and data log readings at a safe distance from hazardous locations. Additionally, it is easier to perform remote tasks such as powering up a device from a control panel that is not nearby. From a time-saving perspective for laptop users, the EX540 permits a user to set up his or her laptop at a centralized location and then sequentially data log readings throughout a site without relocating the laptop. In addition to wireless data logging, can log up to 9,999 readings internally and also reads-Voltage, current, resistance, capacitance, frequency (with dual-range sensitivity for electrical and electronic work), duty cycle (dwell), continuity, diode testing (2.8-Volt), and even temperature (using its Type K thermistor bead probe). Complete with double-molded test leads, USB wireless receiver (914MHz), temperature probe, magnetic hanging strap, 9V battery and carrying case.
