Battery Safety
This instrument is fitted with four size AA batteries either
rechargeable (nickel cadmium) or non-rechargeable
(alkaline).
Before storing this instrument remove the batteries.
When fitting batteries make sure the electrical contacts are
clean and observe the correct polarity.
The battery compartment should be inspected for corrosion
caused by leaking batteries. Corrosion must be removed
using approved methods*.
When storing and transporting batteries make sure that they
cannot be short circuited. A short-circuited battery can
become very hot and can, in certain circumstances, explode.
It is recommended that a suitable container is used for
storing and transporting batteries.
Dispose of old batteries using a safe, approved method.*

Introduction
The Druck UPS-II Loop Calibrator can supply power (source
mode) and produce readings (measure mode) to perform
field calibrations on 2-wire devices.
Operation
For different applications place switches in position as
indicated below:
(transmitters are 4-20mA 2 wire)
The UPS-II has special functions for fixed steps and readings
in %. To open menu press *for 2 seconds. Scroll menu
contents with key and make your choice. Press *again to
confirm your choice.
Note: Functions marked with # are directly available after out or read
selection. Flow = SQ.RT in %.
Press mA/% key to read in mA or %. Press *to select
"continuous" or "fixed steps" in output mode.
Fixed Steps
To output fixed calibration currents in series as indicated
below: choose range from the menu and select "fixed steps".

To output these currents automatically select "fixed steps"
and press keys simultaneously. Time between steps is
10 seconds. Stepping starts at the low end of span.
To return to manual press or .
Valve mode
In the valve mode, stepping will be 3,8 - 4 - 4,2 or 19 - 20 - 21
mA. Select appropriate current to start auto-stepping.
Ramp mode
To output a continuous up/down ramp cycle press keys
simultaneously. Ramp travel time between range limits is 60
seconds cycle starts at displayed value. Press or first
to select start direction. To return to manual press or .
Batteries
Use alkaline or rechargeable NiCad batteries only. The
display shows LOBAT when battery capacity goes low.
CAUTION
DONOT LEAVE DISCHARGED BATTERIES IN THE INSTRUMENT.
OLD BATTERIES CAN LEAK AND CAUSE CORROSION.
WHEN FITTING THE BATTERIES MAKE SURE THE ELECTRICAL CONTACTS
ARE CLEAN AND OBSERVE THE CORRECT POLARITY

Calibration Instructions
General
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-II is a 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-II.
Calibration requires a stable temperature of 21° ±1°C (70° ±2°F).

Calibration Check
1. Check the instrument for accuracy in measure and
source modes, if there is an error greater than the
permitted error, the instrument requires a calibration
adjustment.
Calibration Adjustment
Note: For complete accuracy, the measure mode and source mode adjustment
must be carried together and in the following order.
Measure mode
1. Connect the UPS-II to the electrical calibrator. Switch on
the electrical calibrator and allow it to thermally
stabilise.
2. Switch on the UPS-II and allow the instrument to
thermally stabilise.
3. Select EXT on the LOOP PWR slide switch. Use the
display menu to select the calibration values:
