Product Description
Druck UPS4E Series Loop Calibrator is a rugged and extremely compact loop calibrator, designed to be operated with one hand. It is an essential tool for loop testing/powering process control mA loops and mA devices. Perfect for instrument maintenance with an easy-to-read display and simple-to-use time saving features including step, span and valve check. The UPS4E utilises the most advanced electrical calibration technology to create a dependable, cost-effective loop calibrator.
Display
The graphic display provides a robust design with high contrast back-light for daylight readability.
The unit shows the main measurement with percentage of FS reading.
Measure or source 0 to 24 mA
An internal 24V loop supply is available in both measure
and source modes, essential during plant shutdowns.
In Source mode the current is actively controlled as set by the UPS4E.
In Measure mode the current is controlled by the external equipment being tested.
Simultaneous % readout
Displays mA and the percentage value of 4 to 20 mA or 0 to 20 mA.
Step, span check and valve check
Step quickly through linearity tests and zero/span adjustments. In valve mode, seating can be checked
and the actuator set.
“Fast Set” output
Allows values to be set to within 0.001 mA using the keys. Holding a key quickly ramps the output to the next set point value. This function is ideal for alarm trip tests.
30 VDC measurement
For loop diagnostics and maintenance of voltage output instruments.
Datalogging
Ability to record over 100,000 datalog points of data from the main reading channel. Users can manually activate via the settings menu and configure user set intervals via the display.
Data files can be transferred to a PC for further analysis.
