The Madgetech Volt101A is a compact, low-level DC voltage data logger available in four voltage ranges: ±160 mVDC, ±3.2 VDC, -8 VDC to +24 VDC, and -8 VDC to +32 VDC. The Volt101A features a removable terminal block to allow for simple retrieval of the data logger for downloading while leaving the leads connected. With a ten-year battery life and the ability to store over 2 million time and date stamped readings, this device is ideal for long term deployment and voltage studies.

Connect negative and positive wire leads directly to the terminal port on the Volt101A to monitor and measure voltage levels. The Volt101A is commonly used to assess battery efficiencies or photovoltaic studies to identify how much energy is being created from solar cells.

The Volt101A is compatible with the latest MadgeTech 4 Software making starting, stopping, and downloading simple and easy. Graphical, tabular, and summary data is provided for analysis and can be viewed as customizable engineering units.

***Please note, the IFC200 interface cable is sold separately.***

Password Protection

An optional password may be programmed into the device to restrict access to configuration options. Data may be read out without a password.

Multiple Start/Stop Mode Activation

• To start device: Press and hold the pushbutton for 5 seconds, the green LED will flash during this time. The device has started logging.
• To stop the device: Press and hold the pushbutton for 5 seconds, the red LED will flash during this time. The device has stopped logging.

Alarm

User selectable high and low voltage limits.

Lower Voltage Applications

For lower voltage applications that require a higher resolution, MadgeTech offers the Volt101A 160 mV differential model, which can measure voltage between -160 and 160 mV. The 160mV model is NIST traceable.

Engineering Units

Native measurement units can be scaled to display measurement units of another type. This is useful when monitoring voltage outputs from different types of sensors such as temperature, CO2, flow rate and more.
