UPS III Loop Calibrator
Introduction
The Druck UPS III Series of loop calibrators can supply power
(source mode) and produce readings (measure mode) to
perform field calibrations on 2-wire devices. The set-up menu
enables the user to “source” or “measure” in either voltage or
current and to perform continuity tests. These user
instructions include the operation, safety instructions and
installation requirements for the loop calibrator.

OPERATION
Keys
The key switches the calibrator
on and off. Press and hold for 2
seconds.
The key changes the measure or
source operating mode. Pressing the
keys makes menu selections,
sets numerical values and controls
step and ramp functions (up/down).
The select advanced
functions shown on the bottom of the display. When no key is
pressed for 10 minutes, the calibrator times out and switches
off. To disable this automatic time out, select autpower down

shows the information screen:
Pressing , at this time, the display shows the set-up screen:
The calibrator can be used in two modes
measure or source .
Measure mode
The display shows the measured value; depending on the
settings made in set-up and advanced settings:
When measuring current pressing enables linear or flow,
pressing enables mA or % (value of 4 to 20 mA or 0 to 20
mA).
When measuring voltage pressing changes the resolution
between 0.00V and 0.000V.
To measure continuity the displays shows an open or closed
switch symbol with an audible signal on switch closure.

• Return the loop calibrator to an authorised repair centre
for any repairs, it cannot be repaired on-site.
• To keep the loop calibrator accurate a calibration check
should be carried out once per year.
Cleaning
• Clean the loop calibrator case with a moist, lint-free cloth
and weak detergent.

Calibration Instructions
General
The instrument is supplied by the manufacturer, complete
with calibration certificate(s). A calibration period of 12
months is recommended. The actual calibration interval
depends on instrument usage and the total measurement
uncertainty acceptable for the specified application.
The
UPS-III is a very precise measuring instrument and the test
equipment and conditions of test must be suitable for the type
of work. The calibration check and calibration adjustment
should be carried out in a controlled environment by a
calibration technician*.
The manufacturer offers a comprehensive and, if required,
UKAS accredited calibration service.
* A calibration technician must have the necessary technical knowledge,
documentation, special test equipment and tools to carry out the calibration
work on this equipment.
Calibration Equipment
The following tables give the accuracy requirements for the
calibration equipment and the UPS-III.
Calibration requires a stable temperature of 21° ±1°C (70° ±2°F).

Calibration Check
1.Connect the UPS-III to the electrical calibrator. Switch on the
electrical calibrator and allow it to thermally stabilise.
2.Switch on the UPS-III and allow the instrument to thermally
stabilise.
3.Set the UPS-III to mA measure, adjust the electrical calibrator
to apply the first value in the table 1. Record the reading of the
UPS-III.
4.Repeat step 3 for all the values in the table 1.
5.Compare the recorded values and the applied values. If the
difference is greater than the permitted error, the instrument
requires a calibration adjustment.
6.Repeat this procedure for V measure (table 2) and mA source
(table 3).

Calibration Adjustment
1.Connect the UPS-III to the electrical calibrator. Switch on the
electrical calibrator and allow it to thermally stabilise.
2.Switch on the UPS-III and press , within two seconds to
select Calibration. Enter the access code [9410 factory
setting] and allow the instrument to thermally stabilise.
3.Select the parameter required for calibration. Use the
display menu to select the calibration values. After a
successful calibration enter the new calibration date.
