As this is a Unit Verification Certificate, no QAR is applicable as this certificate is specific to the items listed by serial number or other unique identification.
The UPS-III-IS is designed to measure voltage, continuity or current (in a current loop circuit, either passive or active) of intrinsically safe circuits or generate a current (for a current loop circuit, either passive or active) for intrinsically safe circuits.
The equipment comprises four PCB’s; an encapsulated power supply PCB, an analogue processing PCB, a digital processing PCB and a keyboard and display PCB. Connections between the boards are made by PCB mounted inter-board connectors. The apparatus is powered by four AA Alkaline primary batteries and is enclosed in a moulded plastic housing containing a display window and six push button switches. The plastic housing is further protected by a leather case which must always be fitted when the instrument is used.
The user connections are made to the apparatus by means of four, 4mm sockets situated above the display window for connection of user test leads.
