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 f ield 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.

Safety

This symbol, on the loop calibrator, indicates that the user should refer to the user guide or manual.

Batteries

• Remove batteries from the loop calibrator immediately when discharged and before storage.

• Dispose of batteries in accordance with local regulations and battery manufacturers' instructions.

• When storing and transporting batteries make sure they cannot be short circuited.

Power Supply

The power supply for this loop calibrator can be the internal non-rechargeable batteries or the external Universal power supply unit (see accessories).

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 in the set-up menu.

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.
