GENERAL DESCRIPTION
ALTEK
MODEL 587
DIGITAL MULTIMETER
The  Altek Model 587 is an industrial grade 41/2
digit (20,000 count) highly accurate and reliable
hand-held multimeter .  Its combination of durability
and features makes this multimeter a versatile
solution for all industrial and commercial
applications.  
The Model 587 uses low power CMOS
technology with a LSI circuit incorporating a double
integrating  A/D converter for accuracy and reliability .
The Model 587 measures DC voltage and current,
true RMS  AC voltage and current, resistance,
capacitance, frequency , and diode forward voltage.
The meter also has a beeper for continuity checking.
The basic DC accuracy of this meter is  ±0.05% of
reading, equaling or exceeding that of many 
higher-priced DMMs.  In addition, the 4
1/2digit,
20,000-count display features large 1, high 
contrast digits for easy reading from a distance. 
This high-performance meter also makes true 
RMS  AC measurements on non-sinusoidal signals.
