UPS-III-IS Intrinsically Safe Loop Calibrator
Introduction
The Druck UPS-III-IS 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-IS
Intrinsically Safe Loop Calibrator in a hazardous area. Read the whole publication before starting.

Requirements and Conditions
Refer to the supply and input/output parameter table.
Batteries
WARNING: Only replace batteries in a safe area.
Only use the battery type listed below.
Requirements
Installing should be carried out by qualified plant installation technicians in compliance with the
latest issue of EN 60079-14.
Specific Conditions of Use
1. When user terminal SK7 is used (the 24V output), the external circuit under test, must be
completely isolated from any other sources of power.
2. The remote sensor MUST be isolated from all other sources of power when used in the
fol
lowing operating modes.
• V w.r.t. COM : Continuity measurement.
• mA (24V) w.r.t. mA : Powered current loop, current measurement.
• mA (24V) w.r.t. mA : Powered current loop, current generation.
Loop Calibrator Casing
• Avoid impact sparking when installing in a hazardous area.
• Provide additional protection for calibrators that may be damaged in service.
