Digital-readout power supply
The PTS Electronics DG-1 power supply provides adjustable and regulated DC voltage for testing televisions, stereos, radios, computers, microprocessors, appliances, CB equipment, electronic cash registers, security systems and other electronic devices.
The digital voltage meter is accurate to .05% and indicates to 0.1V. The vinyl cabinet is available in walnut, black or blue and dealer net price is $114.95.
Dual-Trace Scope
A dual-trace, 25-MHz scope, the Telequipment D66A, features a TV trigger switch for television servicing. It allows the operator to obtain a stable display of TV line and field signals quickly. Calibrated sweep speeds range from two seconds to 20 nanoseconds per division; vertical sensitivity ranges from 10 milli volts to 50 volts-per-division. One millivolt-per-division sensitivity may be selected, but bandwidth then is 15 MHz.
The D66A is manufactured by Telequipment, a London-based division of Tektronix, and sells for $1100.
Digital multimeter
EICO has introduced a digital multimeter, model 272. The new multimeter reads out up to 1000 VDC, up to 600 VAC, up to 1000 milliamperes DC and AC, and up to 1 meg resistance on three 0.3-inch bright LED digits. Overrange is indicated by a flashing display. The zero setting is automatic and it is not necessary to operate a switch or reverse the leads when the polarity is reversed as the polarity reading is also automatic. The DMM sells for $69.95.
Sweep/function generator
Model 3020, a sweep/function generator from BSA-Precision re places a function generator, sweep generator, pulse generator and tone-burst generator.
The instrument's frequency coverage spans 0.02 Hz to 2 MHz in seven ranges. Each range provides a linear 1000:1 frequency control.
The operating frequency can be varied on each range by either the front-panel frequency control or by application of a control voltage to its voltage-controlled oscillator external input (sweep function). Almost any wave shape can be generated by the 3020. The square wave output can generate conventional square waves, or be shaped to produce rectangular waves or pulses. A triangle wave can be transformed into a sawtooth (or ramp) and sine-wave distortion can be simulated. All waveform types can be inverted.
Cordless LCD DMM
Simpson Electric Company has introduced a compact, portable digital multimeter. Model 463, priced at $170, is a 3 1/4 -digit liquid-crystal display (LCD) instrument with 26 AC/DC voltage, current and resistance ranges.
The LCD readout and all-LSI circuitry permit up to 200 hours of continuous operation from a 9V alkaline battery. No AC power or battery charger is needed. In addition, the 463 offers 0.2% accuracy for DC voltages plus a wide 20-KHz AC voltage frequency response for audio measurements.
Transient suppression and over load protection is provided for all. It has five DC voltage ranges to 1KV, five AC ranges to 750V, six resistance ranges to 20 meg, five DC current ranges to 2000 mA and five AC current ranges to 2000 mA.
Timing light
Heath Company has announced a new timing light kit for auto tune ups. A single connection to the number 1 spark plug wire is made via a snap-on inductive pickup, so adaptors are not required for model CI-1098. The timing light has its own rechargeable power supply.
A built-in 120/240 VAC recharge able high voltage power supply and xenon flash tube provide a bright flash for easy timing adjustments. A built-in tachometer has a choice of 2000 RPM and 6000 RPM scales.
Portable VOM
BP Electronics has introduced a new VM-547B VOM with a DC accuracy of ± 3 %. AC sensitivity is 10,000 ohms-per-volt. 250 mV ranges and 2.5 volts-full-scale are provided.
Suggested retail price is $29.95.
