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, §Ù, 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.
6 INSTRUMENTS IN 1
-Auto Ranging 4,000 Count True RMS DMM
TPI's 440 has 9 measurement functions and 0.3 basic DC accuracy.
-1 MHz Oscilloscope
View industrial power signals such as motor controls, UPS, switching power supplies, and PLC controls with detail and clarity.
-Trend Mode
Graph readings over a predetermined time period to check for surges or dropouts.
-Component Test
Check voltage-current signatures on capacitors, resistors, semiconductors and much more.
-Logic Test
Indicates transitions up to 2 MHz.
-Frequency Counter
Measure low frequency signals from 1Hz to 2MHz and display duty cycle, pulse width and period.
FEATURES
-T-Base Button:
Use feature to manually adjust sweep speed (time/division) to shrink or enlarge the viewable waveform for analysis.
-Continuous Autoset:
Feature automatically determines the correct vertical and horizontal settings for optimum waveform viewing. Autoset provides hands free operation while moving between test points.
-PC/Printer Compatibility to RS-232C Port:
Optional accessory A402 allows user to download data or waveforms to a PC for archiving, processing, and report generation. Perfect for extended monitoring. Eight waveform storage locations enables remote data acquisition for later viewing.
-True RMS DMM:
True RMS allows the user to obtain accurate measurements of non-sinusoidal AC voltage and current waveform found in controls and circuits.
