UHS Output Jack Description:
The optional output is a 1/8" (3.5 mm) phone jack (mono), which is similar to the jack for headphones. A plug is also supplied which has two bare wires to connect to your data acquisition system or oscilloscope. The output is a slowly-varying signal (1/4 second response time) proportional to whatever the display is reading at the time. It is positive only. For each range (19.99, 199.99 and 1999 milligauss), than output of 199.9 mV corresponds to full scale and 0 mV corresponds to 0 mV.
This meter measures AC magnetic field in a wide frequency range of 13 Hz to 75 kHz (75,000 Hz). The frequencies include most ELF (that is, frequencies below 1 kHz) and VLF (above 1 kHz) magnetic fields. The meter measures the true 3-axis magnitude of the AC field. Two other more specialized measurements can also be performed: 3-axis VLF-only (1kHz – 75 kHz) to measure the strength of higher-frequency fields, and 1-axis full bandwidth (13 Hz – 75 kHz) to determine the principal direction of the AC magnetic field. These specialized measurements are selected by the knob labeled "TYPE OF MEASUREMENT". A "RANGE" knob allows a wide range of field strengths to be measured—from .01 to 1999 milligauss.
Most measurements will be performed with both knobs turned to the left-most position. This setting is for measurement of true magnitude of magnetic field at the widest range of frequencies (ELF + VLF) up to a strength of 19.99 milligauss. If the field becomes stronger than 19.99, most of the display will go blank except for a "1" at the extreme left. This indicates over-range. Then switch the left-side switch to 199.9 (or 1999 if the 199.9 setting still shows over-range).
