Capabilities in detail Automatic or Manual ranging Quick response auto-ranging is provided for all measurement parameters ensuring the best possible resolution at all times. Alternatively manual ranging can be selected. The secondary display can show the range value, giving greater clarity. Wideband True RMS AC True RMS AC gives accurate measurements regardless of the waveform shape.

Capabilities in detail Percentage deviation ( %) This function enables the meter to display the percentage amount by which the reading differs from a nominal value chosen by the user. It is invaluable for measuring tolerance or stability. Automatic data logging The 1908 can store up to 500 readings at any required time interval from 1 reading per second up to 1 reading every 3 hours. A simple recall sequence allows the readings to be scrolled onto the display whenever required.

Remote Interfaces Graphical Interface for PC 1908 - USB interface Both the 1908 and 1908P are supplied with a Windows* based application called “1908-PC Link” that provides a graphical user interface (GUI) for remote control of the meter from a PC. Connection can be via USB, RS-232, or LAN (Ethernet). The 1908 incorporates a USB interface for remote control and readback. The interface is powered from the controlling device enabling the meter to operate from batteries without additional power drain.

Technical Specifications - 1908 and 1908P MEASUREMENT PARAMETERS & ACCURACY Accuracies apply for 1 year 19°C to 25°C. Temperature coefficient outside these limits is <0.1 x quoted range accuracy per °C. Scale Length The scale length is 120,000 counts (unless otherwise stated) giving a maximum measured value for each range of 119999. Thus for the 100V range the maximum measured value is 119.
