Before plugging the monitor into the rear of the UCA, make
certain power to the instrument is off.
If a printer is included with the instrument, it may be connected to the control box.
Connect the USB connector on the printer cable to the control box. The printer
must also be connected to a suitable power source. Refer to the printer
documentation for power requirements.
4.2
Connecting an Uninterruptible Power Supply (UPS)
This is applicable only if there are two receptacles on the rear of the unit labeled
UPS that may be used to connect an uninterruptible power supply (UPS). In the
event of a power failure, the UPS will operate all functions of the UCA, except the
heater, for up to one hour to prevent loss of test. To connect the UPS, select the
power cord supplied with the UPS and connect one end to the UPS input and the
other end to the UCA. The cord will fit only one receptacle. Locate the other
power cord supplied with the instrument and connect one end to the output of the
UPS and the other end to the other UPS receptacle on the rear of the UCA. Press
the ON button on the UPS. A green light will appear on the UPS when it is
operating properly. If the unit beeps and a red light comes on, a power failure has
occurred and the unit is being powered by the UPS. Note that if the POWER
switch is turned OFF and the UPS is not turned OFF, the instrument will not power
down.
If a UPS is not used, the cord must be installed between the two
rear panel receptacles or the instrument will not operate.
Before attempting to operate the instrument, it is recommended that the operators
read the remainder of the manual to become familiar with the UCA operation.
