DigitalBlastingOhmmeters
TechnicalDatasheet
ModelsBO-01,BO-02,BO-03
Features
The Ohmmeters show the blasting circuit resistance
on a large liquid crystal display, which is easily read
in both daylight and poor lighting underground.
� Certificates of approval for BO-01 and BO-02: GME
No. CT2, CIE No. RT1.
� Certificates of approval for BO-03: GME No.CT8.

Operation
�
�
�
Connect the blasting wire to the two terminals and
press the power button. The LCD will display the
resistance of the blasting circuit.
SABS approved and safe for testing electric
initiators at the work face. Permission to do so must
be obtained from the DMR and all MHSA
regulations must be adhered to.
The unit is powered by a replaceable PP3 9V Zinc
Carbon battery and is capable of 200 continuous
hours use on the BO-01 and BO-02 and 20 hours
