American Magnetics 185 & 186 Liquid Level Instruments (CE-Marked) - Manual (Page 12)

Introduction
The length adjustment only affects the scaling of the level display and does
not change the actual calibration of the instrument.
1.1.5 Microprocessor-based electronics
Microprocessor-based electronics provide 0.1% readout accuracy.
Nonvolatile memory maintains instrument calibration without battery
backup. Watchdog timer circuitry and low line voltage (brownout) detector
prevent microprocessor lockup and provide fail-safe operation.
1.1.6 Remote computer monitoring or controlled operation
The Model 185/186 can be optionally equipped with a 0-10 volt recorder
output. A 4-20 mA current loop option is available in lieu of the recorder
output. Available computer interface options include RS-232/422 Serial
Port/Data Logger or IEEE-488.
The Model 185/186 may be optionally configured for a maximum of one
analog output option and one computer interface option.
