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.
