The compact, shockproof, IP54, 3-in-1 Handscope Model OX 5042B can be comfortably held in one hand. The Handscope is an ergonomically designed instrument equipped with a 3.5” color screen with LED backlighting for a precise and crisp data display. Integrated multilingual help screens are available at all times to make it simpler to use.

The Model OX 5042B combines three measuring instruments in one:

• Oscilloscope, 2 fully isolated channels, 40MHz bandwidth, vertical sensitivity 5 mV to 200 V/div
• 2 fully isolated channel multimeter, 8000-count display, with power measurements
• 2 fully isolated channel harmonic analyzer, up to the 31st harmonic (fundamental frequency from 40 Hz to 450 Hz)

AEMC offers its OX 5042B in several packages with additional accessories. The information below provides an overview of main differences in each. All OX 5042B include the necessary probes and test leads for electrical measurements.

The MN251T is a general purpose AC current probe with voltage output. It is designed for use with DMMs or with measuring instruments with voltage inputs. These probes permit the measurement or recording of current with instruments without current ranges. The voltage output is proportional to the current measured (through the jaws). The MN251T offers a voltage output of 1mV per Amp measured. The MN251T has insulated 10ft (3m) coaxial cable terminated by BNC connector.

The MN379T is designed for measuring the secondary of PTs in the 5 A range. It has an upgraded nickel core for improved accuracy and phase shift critical for power applications.

• Max. conductor size: 0.78" (20mm), bus bar 20x5mm
• Current range: 0.005 to 5A, 0.1 to 100A
• Measurement range: 0.005 to 6A, 0.1 to 120A
• Accuracy 50/60Hz: 1% @ 5A, 1% @ 100A

The MiniFlex 3000-24-1-1 is a 24” flexible AC current sensor for measurement of up to 3000A. It features a 10 foot lead, IP50 rating, and an accuracy rating of ±1%.
