This equipment meets the requirements of all relevant European safety directives. The equipment carries the CE mark.

Do not dispose of this product as household waste. Use an approved organisation that collects and/or recycles waste electrical and electronic equipment. For more information:

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.*

Battery Safety

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:

MODE OUT READ EXT. INT. Milliamp. source • • Transmitter sim. • • Milliamp measure • • Transmitter cal. • •

(transmitters are 4-20mA 2 wire)

The UPS-II has special functions for fixed steps and readings in %. To open menu press contents with key and make your choice. Press confirm your choice.

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

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.

UPS-II

is a precise measuring instrument and the test

The 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).

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:
