Wavetek 52A Datalogger
The Wavetek 52A Datalogger combines the
features of up to four digital multimeters with fullfeatured datalogging/data
acquisition capability. Each measurement channel contains a fully isolated
dual slope analog-to-digital converter.
Each input is expandable with multiplexers
to provide up to 260 channels, any four of which can be displayed at one
time. Data on the high resolution liquid-crystal display can be shown in
alphanumeric and bargraph form. All standard multimeter functions such as
resistance and DC and true rms AC voltage and current are included, in
addition to special measurement functions such as temperature, frequency,
period, pulse width, time interval, volt-amperes, dB, continuity, and
diode checking.
Built-in math functions compute and display
delta, delta %, minimum, maximum, or average values. Complex functions
between channels may be calculated with user-defined math. Unique
Close-Box "Flex-Cal" automatic calibration allows calibration at
any value.
Standard datalogging capability allows all
measured data to be stored in internal RAM memory. Optional memory
expansion to over I Meg permits storage of over 100 thousand measurements.
Stored data can be sent to any computer via the standard RS-232 interface.
An IEEE-488 interface is also available. Nested menus, channel list
programming and a real time-clock facilitate selection of functions,
ranges, start and stop conditions, scan intervals, delays, alarms, etc. A
digital I/O option which is combined with an analog output feature is also
available for closed-loop and tracking applications.
All this measurement and data logging
capability is contained in a very small portable package made possible
through the use of an application-specific integrated circuit and
surface-mounted devices. The Model 52A can be operated from a vehicle
battery or any other low-voltage AC or DC source. An internal rechargeable
battery option provides even more versatility. |
