The
2620A Hydra Series II Data Acquisition Unit is a
multi-channel data acquisition unit able to measure ac and
dc voltages, temperature via thermocouples and RTDs,
resistance, and frequency. It features 21 measurement
channels, 8 digital input/output lines, a Totalizer input,
and 4 alarm output lines. The Data Acquisition Unit is
easily carried by hand and can be ac or dc powered. The user
can choose communications with a host computer over an
RS-232 (standard) or IEEE-488 (2620A/05) computer interface.
The
2620A comes with a removable Universal Input Module that
enables fast, convenient set-up and reconfiguration. Any
combination of dc voltage, ac voltage, thermocouple, RTD,
resistance, or frequency measurements can be connected to
the input module without the need for additional signal
conditioning. Thermocouple reference junction compensation
is automatically performed by sensing the temperature of the
input module's isothermal block.
Features:
Channel Scanning: can be continuous scanning, scanning
at an interval time, single scans, or triggered (internal or
external) scans
Channel Monitoring: make measurements on a single
channel and view these measurements on the display
Channel Scanning and Monitoring: view measurements made
for the monitor channel while scanning of all active
channels continues
Multi-Function Display: Left (numeric) display shows
measurement readings; also used when setting numeric
parameters; Right (alphanumeric) display used for numeric
entries, channel number selection and display, status
information, and operator prompts
