High performance digital multimeters

7 May 2003 Test & Measurement News & Events

The MT1000 Series are DMMs that deliver high performance with a wealth of new features, ranges, speed, accuracy and resolution. This range in MajorTech's MT1000 Series meet the IEC1010-1 CAT III 1000 Volt and IEC1010-1 CAT IV 600 Volt safety ratings to withstand overvoltage transients up to 8 kV per IEC 1010-1. The DMMs have a battery access door that allows replacing a fuse or battery without breaking the calibration seal. The overmoulding technology used disperses shock over more of the case than a conventional rubber boot design. The meters all have a standard 'lifetime warranty'.

Both the MT1007 and MT1005 boast 0,05% accuracy and 50 000 counts of resolution on a dual-reading display enhancing troubleshooting with the ability to correlate two relevant events. Their 50 kHz AC bandwidth opens up uses in modern applications not possible with conventional DMMs. Users can also enjoy the high speed when turning a meter on and finding it ready for instant operation. The DMMs have a bright LED backlight as well as an enhanced LCD with larger digits, wide viewing angle and on-screen menu selection. Convenient closed case calibration allows adjustments to be made directly through the RS232C port.

The MT1007 measures volts (DC to 1 µV), ohms, amps, conductance, temperature in °C or °F and capacitance up to 5 mF. Other features include continuity and diode test. The user friendly case design houses a dual reading display with bargraph for simultaneous readouts such as true-rms AC+DC and Hz, dB, mV d.c. and more. Besides relative mode and min/max average, the meter has a 1 ms Fast MIN/MAX for capturing peak transients. In addition it can store up to 10 measurements in standalone operation. The MT1005 is a 5000 count display and measures volts (DC to 10 µV), and has all the same features of the MT1007 except the AC+DC measurement feature.

The MT1003 and MT1001 have 4000 count displays with LED backlight and are designed to withstand falls from benchtops, ladders or other work areas. These two DMMs are perfect for technicians in field service, facilities maintenance and production equipment maintenance/installation. The input ranges and functions are protected to the meters rated voltage so that the user will not blow a fuse or destroy the meter if connected to a live circuit while measuring ohms.

The MT1003 DMM features true-r.m.s. a.c. readings so that one obtains the correct measurement even when harmonics are present. Other features include volts up to 1000 V a.c./d.c., ohms, capacitance, Hz and duty cycle, temperature and amps. A relative mode, data hold, continuity buzzer and diode test are added features.

The MT1001 is an average-responding DMM that has the same features as the MT1003 except no temperature measurement.
