Precision measuring instrument in fitted panel design ALMEMO® 4390-2

Technical data and functions

• Increased measuring accuracy and stability
• Fast measuring rate, up to 50 measuring operations per second. With SD memory card, up to 100 mops, optional for 1 channel up to 400 mops
• 1 ALMEMO^® input socket, suitable for all ALMEMO® sensors or 6-contact clamp connector socket, also for 26 V and 20 mA
• More than 65 standard measuring ranges
• Support for ALMEMO^® plugs with multi-point adjustment, special linearization, and special measuring ranges
• Higher measuring quality thanks to electrical isolation between measuring inputs and device power supply (device ground)
• Data logger with internal EEPROM, sufficient for 16,000 measured values, configurable as linear or ring memory
• Memory connector with micro SD (accessory)
• As standard 2 limit value relays can also be driven via interface
• Option with double analog output can also be driven via interface
• 2 ALMEMO^® output sockets, suitable for digital interfaces, analog output, trigger input, alarm contacts, memory card
• 8-character alphanumeric 14-segment display
• new: Programming functions displayed in normal text (3 languages)
• new: 5 programming menus : Measuring function, memory, sensor, device, output
• Measuring functions : Measured value, dual display, smoothing, zero-setting, setpoint adjustment, maximum / minimum / average values, temperature compensation, atmospheric pressure compensation
• Sensor programming: Measuring range, measured value correction, scaling, units, limit value monitoring, graduated locking of functions, scaling of analog output
• Device programming: Conversion rate, real-time clock with date, output cycle, baud rate, choice of languages
