The family consists of four digital general purpose oscilloscopes with model numbers PM3382, PM3384, PM3392 and PM3394. All instruments have four vertical channels. Differences between these models are the vertical bandwidth, the features of the vertical channels 3 and 4 and the presence of switchable 50Ω input impedance. Vertical bandwidth is 100 or 200 MHz. The ’true 4 channel’ oscilloscopes have four channels with a wide range of input sensitivities. Channel 3 and 4 in the ’4 ...

DYNAMIC CAP TESTING. The “Z METER” is the most reliable capacitor tester on the market at any price. That’s because it is the only tester that dynamically tests capacitors for capacity value, leakage (at full rated voltage up to 600V) and dielectric absorption (a patented test). According to thousands of tests made by Sencore Field Engineers, less than 25% of all capacitor defects cause a value change. Only the “Z METER” steps in to find the remaining 75% that give so muc ...

1.1 Purpose and Usefulness. Designed specifically to meet the need of television, radio and industrial electronics technicians for a compact, reliable, and simple-to-use instrument for testing capacitors, the Sprague Model TO-5 Tel-Ohmike represents the culmination of years of experience in this field. It incorporates in one instrument an accurate multi-range capacitance and power factor bridge, an insulation resistance checker for paper, mica, and ceramic capacitors, and a leakage curre ...
