OV-1
CR5000 Overview
The CR5000 provides precision measurement capabilities in a rugged, battery-operated
package. The system makes measurements at a rate of up to 5,000 samples/second with
16-bit resolution. The CR5000 includes CPU, keyboard display, power supply, and analog
and digital inputs and outputs. The on-board, BASIC-like programming language includes
data processing and analysis routines. PC9000 Software provides program generation
and editing, data retrieval, and realtime monitoring.

FIGURE OV1-1. CR5000 Measurement and Control System
OV1. Physical Description
Figure OV1-2 shows the CR5000 panel and the associated program
instructions. Unless otherwise noted, they are measurement instructions
(Section 7).
OV1.1 Measurement Inputs
OV1.1.1 Analog Inputs
There are 20 differential or 40 single-ended inputs for measuring voltages up
to
±5 V. A thermistor installed in the wiring panel can be used to measure the
reference temperature for thermocouple measurements, and a heavy copper
grounding bar and connectors combine with the case design to reduce
temperature gradients for accurate thermocouple measurements. Resolution on
the most sensitive range is 0.67
