Figure 1. Bump Test/Span Calibration setup
Attach the calibration adapter and connect the calibration cylinder to the IQ Force as shown in Figure 1
. Flow gas to the sensors using a standard
0.5 L/min regulator.
4. Wait for the readings to stabilize. (Forty-five seconds to one minute is usually sufficient. Note the readings. Toxic and LEL sensor readings are considered accurate in a bump test if they are between 90%* and 120% of the expected reading as shown on the calibration cylinder. If the readings are considered accurate, then the instrument maybe used without further adjustment. If toxic or LEL readings do not fall within 90%* and 120% of the expected reading as shown on the calibration cylinder, then the readings are considered inaccurate. If readings are
