Lab-Volt 1242 Laboratory Instrument Dual Power Supply, Digital Multimeter and AF Generator $75 plus shipping or best offer. Shipping weight is 14 US pounds The Lab-Volt 1242 is designed as a general-purpose instrumentation module. It provides just about everything you need except the oscilloscope. This instrument consists of an AF Generator, Autoranging Digital Multimeter & Two Fixed-Voltage DC Power Supplies. Some features of the unit are: An LCD with automatic ranging for the voltage and resistance functions. 3 current ranges can be selected manually. Internal circuit protection is provided on all functions & ranges without use of fuses. The sine/square/triangle function gen. provides a 20 Vp-p adjustable output signal. The frequency coverage is continuous over 20 Hz to 200 kHz in four ranges. The output is protected against overload conditions by internal solid-state circuitry. The DC power supplies provide a highly regulated 15-volt output. Internal thermal overload and short-circuit current limiting provide protection at the output jacks without the use of fuses.

Voltage measurements from 100 µV to 1000 Vdc and 10 mV to 750 Vac (TRMS) o DC volts: Range ±200 mV, ±2 V, ±20 V, ±200 V, ±1000 V; accuracy ±(0.1% of reading + 1 digit); input impedance 10 MΩ; normal mode rejection ratio >60 dB at 60 Hz (50 Hz with 50 Hz option); common mode rejection ratio >90 dB at dc, 50 Hz, 60 Hz 7 o AC volts: Range 200 mV, 2 V, 20 V, 200 V, 750 V; Volts · Hz product 10 max (200 V max at 50 kHz); extended frequency response typically ±3 dB at 200 kHz; common mode noise rejection >60 dB at 50 Hz and 60 Hz; crest factor range 1.0 to 3.0; input impedance 10 MΩ in parallel with <100 pF Current measurements from 100 nA to 2 Adc and 10 µA to 2 Aac (TRMS) o DC current: Range 200 µA, 2 mA, 20 mA, 200 mA, 2000 mA; accuracy ±(0.3% of reading + 1 digit) o AC current: Range 200 µA, 2 mA, 20 mA, 200 mA, 2000 mA; crest factor range 1.0 to 3.0 Resistance measurements from 1 mΩ to 20 MΩ o Range: 200 Ω, 2 kΩ, 20 kΩ, 200 kΩ, 2000 kΩ, 20 MΩ; resolution: 0.1 Ω to 10 kΩ; open circuit voltage: <3.5 V o Low resistance range: 2 Ω (LO Ohms), 20 Ω (LO Ohms); resolution: 1 mΩ, 10 mΩ; open circuit voltage: 16 V maximum Resistance ranges that supply enough voltage to turn on a PN junction for testing diodes and transistors Diode test: 2 kΩ, 200 kΩ, 20 MΩ: These three ranges have enough voltage to turn on silicon junctions to check for proper forward-to-back resistance. The 2 kΩ range is preferred and is marked with a larger diode symbol on the front panel. The three non-diode test ranges will not turn on silicon junctions, so incircuit resistance measurements can be made with these three ranges Conductance measurements up to 10000 MΩ of equivalent resistance: Range 2 mS, 20 µS, 200 nS Automatic polarity indication and overrange indication Protection from overloads and transients up to 6 kV for 10 microseconds Dual-slope integration a/d conversion to ensure noise-free measurements
