TESTS CONDITIONS (datasheet) DUOVAC RADIOELEC Va= 25V Ia=48mA HICKOK TV7D/U
Please note that HICKOK is not a laboratory tester, though it is very well calibrated... HERE is how I calibrated mine following manual services specifications. I calibrated it to respect the low of the scale for filament... High voltage on filament would damage it...but gives higher values... 0.6 (065-0.72) -->0.65V ; 1.1 (1.06-1.16) -->1.14V ; 1.5 (1.26-1.42) -->1.30V ; 2.0 (1.90-2.10) -->1.95V ; 2.5 (2.56-2.88) -->2.77V ; 3.0 (3.25-3.60) -->3.25V ; 4.3 (4.30-4.75) -->4.55V ; 5.0 (5.15-5.68) -->5.49V ; 6.3 (6.20-6.80) -->6.47V ; 7.5 (7.32-8.10) -->7.45V ; 10 (9.60-10.80) -->10.03V ; 12.6 (12.1-13.3) -->12.25V ; 20 (19.0-21.0) -->20.50V ; 25 (25.3-28.0) -->27.65V ; 35 (35.2-39.0) -->38.09V ; 50 (51.5-57.0) -->52.80V ; 75 (74.0-82.0) -->74.82V ; 117 (115-127) -->116.5V If needed, i can share all other tests calibrations I get (129.5V/130V +o-3V ; 41.35V/40V +o-2V ; 4.21V/4V +o-1V ; 56.5V /56V....) |
