(DVA) Overview  Peak Reading Voltage and Resistance

NOTICE: The resistance readings given are for a room temperature of 68 degrees Fahrenheit. Higher temperatures will cause a slightly higher resistance reading. DVA readings should always be taken with everything hooked up.
The CDI peak reading voltage adapter is specifically designed to work with FLUKE AUTO Digital VOLTMETERS. This adapter will simplify the testing of electronic Ignition systems, stators, and sensors. The peak voltage readings will be approximately the same as any other peak voltage meter, and the specifications in the test manuals can be followed without any major problems. STEVENS INSTRUMENT accessories for the CD-77 peak reading volt meter, SA5, SA6 (CDI#511-9756) and PL88 (CDI#511-9775), along with the CDI 511-9770 piercing probes are highly recommended for use with this adapter.
Instructions: Plug the adapter into the Fluke digital volt meter with the rib (+) plug in the (v, Ohms, *) jack, and the other plug in the (COM) jack. Set the switch on the Fluke meter to the DC voltage setting and connect the probes to the test points to be measured. This adapter will automatically compensate for polarity and all readings will be peak voltage. The Fluke meters are auto ranging and will read the proper voltage level without changing ranges. See the attached list of readings and instructions for testing most OMC and Mercury Outboard Ignition systems. Other ignitions can be tested if the manuals give peak voltage readings or is you test a known good Ignition system.
