Page 3: Introduction
A precision voltage to current converter maintains precise calibration over the full range of operating temperatures. The Mag-01H differs from the Mag-01 due to the addition of a x10 sensitivity control to increase resolution and the provision of a precision offset control to expand the measuring range. -
Page 4: Power Supplies And Battery Charging
Power supplies and battery charging The instruments are powered either continuously from the mains, via a power supply, or from the internal 6V rechargeable battery. The battery provides more than 12 hours continuous use. It can be recharged at 12V either from the mains or from a vehicle battery. -

±1__________. The sign is preserved but only the leading 1 will be displayed. Analog output - See figure 1 The Mag-01 is primarily intended for the long term precise investigation of static or slowly varying, low intensity magnetic fields. The frequency response of the instrument is tailored to remove noise from high frequency sources. -
Page 6: Vector Sensing
Vector sensing The cores within the probe only respond to the component of a magnetic field which is along the axis of the cores. The probes are therefore vector sensing and produce a cosine directional response. The measured value V = Bmax Cosθ where Bmax is the total field strength and θ... - Page 7 Special probe type D/S possesses a shorter (9mm) sensing element and, when used in conjunction with the Mag-01(H) specially set up for the purpose, will permit measurements using the analog output of up to ±5.3V, equivalent to ±5.3mT, with the probe at a temperature no higher than 25 C.

Page 8: Conventions
Mounting the Cryogenic Probe The probe can be mounted by bonding, using a minimal mount epoxy adhesive, or by loosely supporting the probe within a tube. Proximity Effects No two Mag cryogenic probes should be operated within 10mm of each other if interaction is to be avoided. -
Page 9: Battery Replacement
Instructions for battery replacement Remove the two case retaining screws in the base of the instrument and remove the top cover. Disconnect the battery leads (Mag-01) or the battery connector (Mag-01H) and fit a replacement battery. Re-connect. 4.2 Electromagnetic compatibility The Mag-01 and Mag-01H instruments contain no high frequency electronics likely to cause emissions which could affect other apparatus. -
