TESTS CONDITIONS (datasheet) DUOVAC RADIOELEC Va=250V Vg=-8,5V b'&' (-5V) Ia=10,5mA b'&' (20mA) HICKOK TV7D/U EV7-6080 B24 B min=56 (65%) (100%=93) EV2-1030 B24 B min=56 (65%) (100%=93) 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) --b'>'0.65V; 1.1 (1.06-1.16) --b'>'1.14V; 1.5 (1.26-1.42) --b'>'1.30V; 2.0 (1.90-2.10) --b'>'1.95V; 2.5 (2.56-2.88) --b'>'2.77V; 3.0 (3.25-3.60) --b'>'3.25V; 4.3 (4.30-4.75) --b'>'4.55V; 5.0 (5.15-5.68) --b'>'5.49V; 6.3 (6.20-6.80) --b'>'6.47V; 7.5 (7.32-8.10) --b'>'7.45V; 10 (9.60-10.80) --b'>'10.03V; 12.6 (12.1-13.3) --b'>'12.25V; 20 (19.0-21.0) --b'>'20.50V; 25 (25.3-28.0) --b'>'27.65V; 35 (35.2-39.0) --b'>'38.09V; 50 (51.5-57.0) --b'>'52.80V; 75 (74.0-82.0) --b'>'74.82V; 117 (115-127) --b'>'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....)
