Works with a variety of power supplies, such as an AC adapter or logic terminal For operation, convenience is the key. Operating power for the DIFFERENTIAL PROBE 9322 can be supplied from the standard logic terminals of a MEMORY HiCORDER or the clamp sensor input terminals of an F/V UNIT 8940, as well as from the probe's own AC ADAPTER 9418-15. Fl o a t i n g m e a s u r e m e n t of h i g h -vo l t a g e waveforms (DC mode) When measuring the potential difference in signals containing a large common mode voltage component on commercial power lines, an electrocution hazard exists unless measurement is done using an instrument with fully isolated inputs, such as a MEMORY HiCORDER. When measuring signals carrying common mode voltages with a high frequency component (such as those produced by inverter control circuits and switching power supplies), measurements are greatly affected by the rate of common mode elimination at the isolated inputs. Although MEMORY HiCORDERs provide the greatest possible to-ground voltage rating (ordinarily 400V AC or DC), use of the DIFFERENTIAL PROBE 9322 raises the rating level to 1500V AC (CAT II), 600V AC (CAT III), allowing measurement of circuits carrying even larger common mode voltages. Potential differences can be measured for input voltages of up to 2000V DC or 1000V AC (CAT II), 600V AC/DC (CAT III), producing a 1/1000 divided output. Measurement of power line surge noise (AC mode) Upon selecting the AC output mode, the AC coupled signal inside the probe is divided by 1000 for output. Since the probe's frequency range is from 1kHz to 10MHz, output waveforms are produced only when input voltages contain high frequency components, such as surge noise imposed on 50/60Hz commercial mains power. The probe can thus serve as either a noise detector or for measurement of wave peaks. Provides output of true RMS rectified voltages (RMS mode) Upon selecting the RMS output mode, the input signal is divided by 1000, rectified to obtain the true RMS value, then output as a direct current voltage. True RMS rectification is performed by an analog circuit with a bandwidth of 40Hz to 100kHz, allowing true RMS conversion of signals containing high frequency components, such as inverter output waveforms, as well as 50/60Hz commercial mains. 3-phase inverter output circuit (Floating measurement is essential due to varying emitter potentials of each phase.) 3-phase inverter waveform recording example 3 Dimensions and mass: approx. 70 (2.76in) W × 150 (5.91in) H × 25 (0.98in) D mm, approx. 350g (12.3oz) Cable length: Main unit cable 1.3 m (4.27 ft), input section cable 46 cm (1.51 ft) Basic specifications (Accuracy at 23 ±5°C/73 ±9°F, 35 to 80% rh, after 30 minutes of warm-up time; accuracy guaranteed for 1 year) DC mode Measurement functions (1) DC mode, (2) AC mode, (3) RMS mode Application Waveform monitor output Input type Balanced differential input Frequency characteristic DC to 10 MHz, ±3 dB DC amplitude accuracy ±1 % f.s.
