  • Page 13: About The Meter

    BOUT ETER 2.1 DESCRIPTION The meter is a fully programmable ratemeter/ totalizer/ controller with six-digit resolution for totalizing input pulses or rate measuring. Alphanumeric display prompts make it easy to program with front-panel buttons. You may use a personal computer to program the meter and monitor the display data using the RS-232 option. You may store the program setup in the nonvolatile memory for recall upon demand or at power- The crystal timebase is electronically calibrated.
