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 versatile handheld TPI 440 is a customer winner.

Technicians appreciate the bright backlight of the 3″ x 3″ cold cathode flourescent display and rugged construction inside and out.
