Usage Instructions:
1. Display:
The graphic display provides high contrast back-light for
daylight readability. It shows the main measurement with percentage
of FS reading.
2. Measure or Source 0 to 24 mA:
An internal 24V loop supply is available in both measure and
source modes. 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.
3. Simultaneous % Readout:
The display shows mA and the percentage value of 4 to 20 mA or 0
to 20 mA.
FAQ:
Q: Can the UPS4E calibrator measure voltage?
A: Yes, it can measure voltage with a resolution of 0.001.
Q: What is the internal memory capacity for datalogging?
A: The UPS4E has an internal memory capacity of 100,000 points
for datalogging.

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.
Step mode 4 to 20 mA linear 0 to 20 mA linear 4 to 20 mA flow 0 to 20 mA flow 4 to 20 mA span check 0 to 20 mA span check 4 to 20 mA valve 0 to 20 mA valve

Auto step and ramp
Outputs have adjustable ramp/step rates (1 to 599 seconds) for singlehanded loop testing, valve set-up and slew rate checks.
“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.
Other features
· Industry standard AA batteries · Supports inrush current to a max of 40 mA for 500 ms · Battery status indicator · Information screen reports serial number, software version
and calibration date · PIN protected calibration and firmware updates.
