Will the Dale 900/ Impulse 3000 test biphasic defibs?
Yes, all Dale 900 defib analyzers will test biphasic defibs. The Impulse 3000 will test biphasic defibs depending on the firmware version. The firmware version is briefly displayed at power up. Firmware versions earlier than version 1.08 were not tested but are considered to be incompatible. Version 1.10 is also not compatible. These versions will generally give you inconsistent and usually low joule output readings when you fire your biphasic defib. Versions 1.11 higher will be compatible with biphasic defibs.
