Pocket Cricket
Sencore has introduced a pocket-sized transistor tester. Battery-operated, the Pocket Cricket is designed to check nearly all transistors and FETs either in or out of circuit.
An automatic circuit turns the instrument off after 10 minutes of use to save batteries. The unit can be ac-operated on the bench with an optional PA208 power adapter.
Benchtop DMM
A 3 1/2-digit benchtop digital multi-meter can measure ac or dc currents up to 20 A. Model 1351 from Data Precision has 0.1 % basic accuracy. Featuring 34 ranges, it can measure dc volts from + 100 pV to 1200 V, ac volts from 100 uV to 1000 V RMS and resistance from 100 Mc to 20 M S2 with either high or low voltage. Measurements are displayed on a 0.43-inch LED display. Model 1351 is complete with test leads and spare fuse and is priced at $199.
Debounce switch
Cincinnati Electrosystems' model 395 Debounce Switch provides a method for clocking logic circuits without contact bounce. A push button switch generates a choice of a positive or negative 10 ps pulse or a level change. The instrument is priced at $7.95.
Digital multimeter
Model LM-353 3 1/2-digit digital Volksmeter from Non-Linear Systems is packaged in a 1.9"x2.7"x4" plastic case. Basic functions include ac and dc volts, ohms, and ac and dc mA. Full-scale ranges are 1, 10, 100 and 1000 mA.
Low-power ohms provide in-circuit tests of resistive components. The unit utilizes an LCD display. Replaceable AAA size batteries allow up to 100 hours of operation. The LM-353 sells for $149.50.
