Use this button to turn the Check and Go on and off. When the Check and Go is in the Sleep (power off) mode, the LCD display is blank. The analyzer turns off after 1.3 minutes if no buttons are pressed.
Check and Go. In Line Calibration (Configuration A) 1. Put the Check and Go in an upright position such that you can read the product label. 2. Connect a sample supply hose to a standard "T" piece. The Drive "T" is precision-tapered to insure a tight connection with O-rings of the MAX-250 oxygen sensor diverter.

30 seconds, allow at least 2 minutes to ensure that the sensor is completely saturated with the calibration gas. 6. If the Check and Go is not already turned on, do so now by pressing the analyzer ON button.
3. Start the flow of the sample gas to the sensor. 4. Allow the oxygen sensor to remain in the flow of the sample gas until stable. 5. If the Check and Go is not already turned on, do so now by pressing the analyzer ON button.
"false " calibration value. Make sure that the calibration gas is connected to the Check and Go at 2 liters per minute for a minimum of 2 minutes prior to proceeding with calibration. This 2-minute equilibration time is necessary to insure that the sensor is completely saturated with the calibration gas.
Calibration Errors and Error Codes The Check and Go analyzers have a self test feature built into the software to detect faulty calibrations, oxygen sensor failures, and low operating voltage. These are listed below, and include possible actions to take, if an error code occurs.
500 feet. Effects of Temperature The Check and Go will hold calibration and read correctly within ±3% when in thermal equilibrium within the operating temperature range. The device must be thermally stable when calibrated and allowed to thermally stabilize after experiencing temperature changes before readings are accurate.
The Check and Go oxygen sensor has been validated at pressures up to 2 atmospheres absolute. Calibration or operation above this pressure is beyond the intended use. Humidity Effect Humidity has no effect on the performance of the Check and Go other than diluting the gas, as long as there is no condensation.
General Specifications Sensor Type: Drive galvanic cell w/Temperature Compensation (non- replaceable) 0.0 - 99.9% oxygen (gas). Measurement Range: Resolution/ 0.1% - The three digit LCD indicates values between 0.0 - 99.9% oxygen. Over range indicated by one decimal point Display: on display located after the first digit.
Drive warrants the Check and Go to be free from defects of workmanship or materials for a period of two (2)-years from the date of shipment from Drive, under normal operating conditions and provided that the Check and Go is properly operated and maintained in accordance with Drive’s operating...
