Specifications are from and may vary slightly due to upgrades. Options, or revisions this unit may or may not have. This set is guaranteed to work for 30-days. Parts and labor, excluding freight. Link to the Manual: Link to the Manual: Description: An HP 339A with Option 001 installed is a standard 339A Distortion Measurement Set with two additional voltmeter input ranges. These ranges are.3 mV and.1 mV full scale. Measurement capabilities are from.1 mV rms full scale to.3 mV rms full scale in a frequency range of 10 Hz to 80 kHz. And from.001 V rms full scale to 300 V rms full sclae in a frequency range of 10 Hz to 110 kHz. When switched to the.3 mV range. The voltmeter attenuator is set to 0 dB. When switched to the.1 mV range, the voltmeter attenuator remains at 0 dB and 10 dB of gain is added to the input amplifier. This gives the required input for full scale deflection on the front panel voltmeter. These changes in voltmeter range have been accomplished by adding two additional positions on S4 of the Analyzer/Power Supply printed circuit assembly. Distortion Specifications: Fundamental Frequency Range: 10 Hz to 110 kHz continuous frequency coverage in 4 decade ranges with 2-digit resolution. Distortion analyzer and oscillator are simultaneously tuned. Distortion Measurement Range: 0.01% full scale to 100% full scale(80 dB to 0 dB) in 9 ranges. Detection and Meter Indication: True rms detection for waveforms with crest factor Option 001 Specifications: Voltage Range: Standard: 1 mV rms full scale to 300 V rms full scale(60 dB to +50 dB full scale. Meter calibrated in dBV and dBm into 500 ohm) Option 001: 1 mV rms full scale to 300 V rms full scale(80 dB to +50 dB full scale. Meter calibrated in dBV and dBm into 600 ohm) Accuracy: Standard: INPUT RANGE.001 V to 300 V 20 Hz to 20 kHz: ±2% 10 Hz to 110 kHz: ±4% Internal Noise Floor: O

Distortion components are typically 0.1% 2nd and 0.05% 3rd which are low order and not audible making the TS2 useful in making listening tests where a function generator would generate undesirable, audible side effects. Full frequency sweeps can be made from 20Hz- 20kHz in a single range. These units have no amplitude changes over the entire frequency range. Frequency range: 10Hz- 30kHz Accuracy: ± 0.1dB from 20Hz- 20kHz. Output impedance: 50 ohm unbalanced. Optional balanced available. Adjustable output level: 70dBv to +18dBv ref: 0.775V) Maximum output level: +18dBv@ 2k ohm or greater. +16.5dBm@ 600 ohms. Distortion: The Frequency Counter: The frequency counter is internally connected to the internal oscillator and displays the oscillator frequency until a signal is plugged into the input connector. It then displays the frequency of the input signal. The frequency counter is disabled below 40dB to avoid induced count errors. Below 10KHz the counter updates mice a second. Above 10KHz it updates ten times per second. This unique combination of Frequency Counter and Audio Oscillator affords absolute precision in setting frequencies. Frequency response: 1Hz-99

Battery operated meter useful to every sound contractor or installer, this unique instrument will make measurements on 25, 50, 70, or 100 volt line systems. Sine waves are generated at 100 Hz, 330 Hz, 1 kHz, or 10 kHz to read impedance or calculated watts. A selector switch allows 200, 2k, or 20k ohm range for better accuracy. The LCD display has a low battery indicator. To assure that any distributed system is properly wired and presenting the correct impedance to the amplifier(s) the installer has the choice of reading the impedance in ohms or the calculated watts that the system should draw. For example, if the tap on the transformer is wired for 5 watts and a total of 10 speakers wired the same way are installed in the system, the ZM-1 will read 50 watts. Net wt. 3/4 lb.

This is a clean unit in working order. A service manual is included. But no test leads are included. I purchased this meter used many years ago. The seller had sent the meter to TOA for repair at one point. TOA replaced the meter movement, but ran out of the labels for the switches. A fax from the seller to me states this fact, and he goes on to explain the function of the 4 pushbutton switches. It’s simple really; from left to right they are, off, x1, x10, x100.
