CellarSafe Calibration, testing and routine maintenance VI Calibration, testing and routine maintenance 6.1 Functional Testing For optimum performance, it is recommended that Cellarsafe is calibrated every six months using the Cellarsafe calibration unit. A minimum requirement is that units are functionally tested as described below. However, it should be noted that full re-calibration may be required after 3 - 4 years of use. -
Page 18: Calibrating The Cellarsafe Gas Monitor
Calibration, testing and routine maintenance CellarSafe requires calibration gases and a pair of bayonet calibration adapters. In calibra- tion mode all alarms and relays are inhibited. Calibration gases Zero calibration is performed using 100% nitrogen. Span calibration is per- formed using a gas mixture comprising 4.0% carbon dioxide and 20.75% oxygen with a balance of nitrogen. - Page 19 CellarSafe Calibration, testing and routine maintenance Step 1: Connecting the Calibration Unit 1 Switch off the mains supply to the CellarSafe base unit and any ancillary equipment connected to the alarm relays. 2 Remove the front cover and disconnect the battery if fitted. 3 Plug the lead from the calibration unit into the connector marked “PL2”...
- Page 20 Calibration, testing and routine maintenance CellarSafe The base unit is now in calibration mode, the operator display panel will display alternately the internal temperature of the instrument and the gas reading. 2 If the Zero Calibration LED is not lit, press the Scroll/Power button. 3 Apply zero calibration gas as described in step 2 above, and wait for the gas reading in the operator display panel to stabilise.
- Page 21 CellarSafe Calibration, testing and routine maintenance 6 Switch off the calibration unit by pressing the Scroll/Power button once, and then press and hold Scroll/Power button 3 seconds. Both LEDs will extinguish. Step 5: Calibration Unit disconnection 1 Press and hold Scroll/Power button for 3 seconds to switch off the mains electrical supply to the base unit.
