TPI 440 Oscilloscope 1 MHz True RMS DMM Logic And Component Test Leads And Charger - 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.
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 resistors, capacitors, and semiconductors.
Logic Test: Indicates transitions up to 2 MHz.
Frequency Counter: Measure low frequency signals from 1Hz to 2 MHz and display duty cycle, pulse width and period.
PC/Printer Compatibility to RS-232C Port Optional accessory A402 allows user to download data or waveforms to PC for archiving, processing, and report generation. Ideal for extended monitoring.
Approvals: Meets CE and IEC 1010 requirements
True RMS: Needed to accurately measure non-sinusoidal AC voltage and current waveforms found on many control and circuits
Auto Set: 440 automatically sets-up the scope depending on the magnitude of the signal being measured
Real Time Update:Tracks events as they happen
Glitch Capture: Finds spikes in signals
Relative Mode: LCD displays the difference between the measured value and a stored value
Trend Mode: Graphs signals to find problems with circuits
Record Mode: Records Min/Max and Average values. Time reference when value was obtained
Compare Mode: Compares stored value with measured value for matching components
Relative % Mode: Displays measured value as a percentage of stored value for checking component tolerances
RS232 Output: Transfers data directly to a PC while measuring
Back Light: Allows viewing in any light condition
Autorange: Automatically selects best range for measurement
Low Battery Indicator: Battery should be charged when battery symbol displays on LCD
