TPI 440 Scope Plus Digital Multimeter

The TPI 440 is a hand-held oscilloscope plus autoranging DMM. The instruments large, backlit LCD display shows a reading and waveform simultaneously. 

In addition to the standard functions of ACV, DCV, ACA, DCA, Ω, Diode Test and Continuity Buzzer; the 440 measures Frequency (Hz),Capacitance, Logic and Component test functions. The 440 also has RS232 output and software for interfacing with a PC is offered as an optional accessory.

The TPI 440's DMM function can be used to test DC and AC voltage to 1000V, DC/AC current to 10A, resistance to 40MΩ, capacitance to 400μF and frequency up to 2mHZ. The digital multimeter is true RMS, autoranging and has basic DC accuracy of 0.3%.

As an oscilloscope, the TPI 440 can be used to view industrial power signals such as motor controls, UPS, switching power supplies and PLC controls. This information is displayed clearly as waveform analysis, allowing the user to track voltage vertically and horizontally to detect swells, dips and unexpected errors.

The TPI 440 Multimeter Is Supplied With:

  • TPI 440 True RMS Digital Multimeter/Oscilloscope
  • Insulated Test Leads with Alligator Clips
  • Power Supply
  • NiCad Battery
  • Instruction Manual
