performance. If the deviation is beyond the declared specification, it is permitted to return it to factory for re-
pair or calibration.
Before verification, please connect the Gima Vital Signs Monitor to a precise pressure meter such as a mercury
pressure mete, which is used as the reference meter.

Mode 1: Automatic inflation
The inflation can be activated by Gima Vital Signs Monitor so the pressure will increase automatically until it
exceeds the limit value specified in table A. This pressure limit value depends on the patient type selection as
shown in table A:
Table A
During inflation, the Gima Vital Signs Monitor will close the deflation valve, and pressure reading will be shown
as inflation takes place. If there is no manual deflation operation, the pressure will persist until deflation by the
manual valve. It is necessary to deflate in several steps to verify the pressure accuracy at points across the full
scale measurement range.
Mode 2: Manual inflation.
Increase the pressure manually by the inflation balloon, and the verification can be done by applying different
pressures manually. If the increased pressure exceeds the given limit as shown in table B, the Gima Vital Signs
Monitor will deflate automatically because of the over-pressure protection valve in each mode.
