DO4A
Rugged, portable digital ohmmeter digital with
calibration and 4,000 count
The DO4A 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, digital calibration and long scale
length (4,000 count).
The rechargeable sealed lead acid battery means real portability with
more than 14 hours continuous operation. Full measurement capability is
maintained while 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. The test leads provided have a
length of 1m 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.
