UPS-III Intrinsically Safe Loop Calibrator
Introduction
The Druck UPS-III Intrinsically Safe Loop Calibrator 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 instructions detail the requirements
and operation of the UPS III Intrinsically Safe Loop Calibrator
in a hazardous area. Read the whole publication before
starting.

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 loop calibrator times out and
switches off. To disable this automatic time out, select
autpower down in the set-up menu.

Maintenance
• Return the loop calibrator to an authorised ATEX 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 leather case with a moist, lint-
free cloth and weak detergent.

Battery Replacement
WARNING: ONLY REPLACE BATTERIES IN A SAFE AREA
Only use the battery type listed on page two.
Unscrew and remove the securing screw from the battery panel.
Replace the batteries, check the polarity of the batteries. Refit and
secure the battery panel.

Calibration Instructions
WARNING:
CALIBRATE UPS-III-IS LOOP CALIBRATORS IN A SAFE AREA.
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 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-IS.
Calibration requires a stable temperature of 21° ±1°C (70° ±2°F).

Calibration Check
1.Connect the UPS-III-IS to the electrical calibrator. Switch on
the electrical calibrator and allow it to thermally stabilise.
2.Switch on the UPS-III-IS and allow the instrument to thermally
stabilise.
3.Set the UPS-III-IS to mA measure, adjust the electrical
calibrator to apply the first value in the table 3. Record the
reading of the UPS-III-IS.
4.Repeat step 3 for all the values in the table 3.
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 4) and mA source
(table 5).
Calibration Adjustment
1.Connect the UPS-III-IS to the electrical calibrator. Switch on
the electrical calibrator and allow it to thermally stabilise.
