Description

The Arbra DO 2000 is a portable Ohmmeter designed to be used for measuring the resistance of electric detonators. It is designed to safely test shot firing circuits without the danger of pre-initiation. Resistances up to 1999 Ohms may be measured. It is made using surface mount technology package for all its electronic functions. It has a self-setting zero and a low battery warning.

The Arbra DO 2000 has been locally tested by SIMTARS and complies with AS 2187.2:2006 clause B4 (Equipment for electrical firing – Circuit Tester).

Simple Operation

To operate the Ohmmeter, connect the shot firing cables to the two terminals. Press the switch button to see the circuit resistance displayed. The unit automatically switches off when the button is released. An open circuit or resistance above 1999.9 ohms is displayed as an O:C in the middle of the display. When the battery requires replacement a battery symbol will appear on the display.

Construction

The DO 2000 is manufactured in a robust high-impact ABS moulded case. It is water and dust resistant. A unique feature of the DO 2000 Ohmmeter is the use of sliding billet terminals. This feature makes for ease in connecting cables to the exploder and also helps prevent the cables from damage. Components inside the ohmmeter are encapsulated to protect against damage from mishandling reducing maintenance to a minimum.

The DO 2000 is suitable for general blasting applications including construction and quarry. It is not suitable for underground coal environment.

Specifications

NB: IT IS THE SHOT FIRER’S RESPONSIBILITY TO ENSURE THAT RELEVANT STANDARDS AND APPROVED SAFETY PROCEDURES ARE OBSERVED. THE DEVICE IS INTENDED TO BE USED BY QUALIFIED PERSONNEL ONLY FOR GENERAL BLASTING APPLICATIONS. NOT SUITABLE FOR UNDERGROUND COAL ENVIRONMENT.

The Arbra DO 2000 is available from Stantron. Contact Stantron for further details.
