B&K Precision Electronic Multimeter Model 277 - Tested and Working VGC - Unit comes with the original DYNASCAN PR-21 Probe - VGC - Please see all photos. An electronic copy of the manual is included.


Condition: Excellent tested AC/DC voltage, A/ma and R against know standards, the analog meter was within 2% on all functions checked! I've had this one for a while and its always been accurate if you carefully zero the meter prior to observing the results. Case is in exceptional shape as well.


PR-21 probes are hard to find, they were sold with the 277 with later years production. It's a 10:1 / direct probe for scopes and meters, rated 10 MHz / 500v. I've see just the probes sell for quite a bit. Keep in mind these probes have shielded cables, that provide more accurate measurements including lower voltages, for example.
