Model 440 Scope Plus
- 6 Instruments in 1 -
1. Auto
Ranging
4000 Count True RMS DMM - TPI's 440 has 9
measurement functions and 0.3% basic DC accuracy. True RMS capability
allows the user to obtain accurate measurements of non-sinusoidal AC
voltage and current waveforms.
2. 1 Mhz Oscilloscope - View industrial power signals with
clarity on the scopemeter display. Simple-to-operate oscilloscope function provides a "picture" of
voltage or current waveforms making it easy to detect system problems such
as harmonics and waveform distortion.
3. Trend Mode
- Graph reading over a predetermined time period to check for the presence
of undesirable voltage or current variations.
4. Component Test
- (Curve Tracer) Check voltage current signatures on capacitors,
resistors, and semiconductors.
5. Logic Tests -
Indicates TTL and CMOS logic level tranisitions up to 2 Mhz.
6. Frequency Counter
- Measure frequency from 1 Hz to 2 MHz and display duty cycle, pulse
width, and period.
Features
Double Insulated and Battery Powered - Safe waveform analysis on Industrial
Equipment to 600 VAC including: DC Motor Drives, Generator Excitation Systems,
Variable Frequency Drives ( VFD's), and Soft-Starts.
Easy to Operate - Auto Mode Function for quick set-up. Menu-Type
Function Keys simplify input setting selections and triggering.
Simultaneous real-time, digital display of scope parameters permits quick,
accurate waveform measurements without calculations.
