"This portable Digital Milliohmmeter is a practical instrument for low resistance measurement, ideal for use in the workshop, field or test facilities. It is of rugged construction contained in an aluminium case with tilt handle. The DO4A has many advanced features, including protection up to 415 volts rms, digital calibration and long scale length, 4000 count. The test leads provided have a length of 3 feet with spade tags for connection to the ohmmeter terminals. They are terminated in combined current and potential probes that will accept conductor diameters up to 6mm. The rechargeable sealed lead acid battery means real portability with more than 14 hours continuous operation, without the problems normally associated with other battery types. Full measurement capability is maintained whilst charging. For ease of operation the control functions have been kept to a minimum and are clearly marked. It is of course direct reading, warning LEDs illuminate when an open circuit lead condition is detected. Over range and low battery indication is also provided. The DO4A is supplied ready for immediate use with battery, mains cord and measuring leads, no extras are normally necessary. The 15mm LCD provides easy viewing and the instrument can be used in any position for many and varied applications."
