Calibration
WARNING
Health hazard due to test gas
Inhaling test gas may risk health or lead to death.
► Do not inhale test gas.
► Observe risks and security statements related to the test gas (Refer to data
sheets and instructions figuring on calibration devices).
CAUTION
Triggering alerts by test gas
Applied test gas may trigger alerts.
► Make sure that test gas is no longer applied after calibration.
Supplies:
– Test gas cylinder with pressure reducer, for corrosive gases with stainless
steel pressure reducer
– Calibration adapter with hose nozzles (order no. 68 10 536)
– Hose, type according to the gas property (e.g., FKM hose, order
no. 12 03 150)
Prepare the test gas supply:
1. Connect the calibration adapter (Fig. G 2) and test gas cylinder (Fig. G 4) to
the tube (Fig. G 3).
2. To discharge the test gas, connect a hose to the second connector on the
calibration adapter.
3. Attach the calibration adapter to the sensor (Fig. G 1).
11.3

Zero calibration with oxygen

In the case of O sensors, the zero-point is only checked (not calibrated) when
2
nitrogen is applied to the sensor. The gas detector indicates an error condition if
0.6 Vol% O is not undershot. In the event of an error, repeat the zero
2
calibration or change the sensor.

11.4

Carrying out the zero calibration

Prerequisites:
– The test gas supply has been prepared.
– A connection between the gas detector and PolySoft has been established.
Carrying out the zero calibration:
1. Start zero calibration in PolySoft.
®
 WirelessHART
interface transmits the device variable status "Bad" and
the special status "Calibration".
2. Follow the instructions of the wizard In PolySoft.
Flow with test gas supply: 0.5 L/min ± 10 %
3. After completion of the zero calibration, switch off the gas flow and remove
the calibration adapter.
11.5

Carrying out the span calibration

Prerequisites:
– Zero calibration has been carried out.
– The test gas supply has been prepared.
– A connection between the gas detector and PolySoft has been established.
Carrying out the span calibration:
1. Start and confirm span calibration with PolySoft.
®
 WirelessHART
interface transmits the device variable status "Bad" and
the special status "Calibration".
2. Follow the instructions of the wizard In PolySoft.
Flow with test gas supply: 0.5 L/min ± 10 %
3. After completion of the span calibration, switch off the gas flow and remove
the calibration adapter.
