MGC 100/200 Notes Instruction 0019-9322
MGC 100/200 1.0 INTRODUCTION 1.1 General Bacharach analyzers are easy to use, but it is essential that these Operating Instructions be read and understood by all operators and maintenance personnel prior to using or servicing the instrument. The Bacharach MGC series of monitors are versatile handheld instruments that are designed to measure N2O, CO2 and CO from piped medical-gas outlets.
MGC 100/200 1.3 Applications • Piped medical gas checking 1.4 Instruction Manual Unless otherwise noted, all paragraphs in this instruction manual describe the operation and maintenance of both the MGC 100 and MGC 200. For example, the heading 2.9 Battery Charge Display (MGC 100) indicates that the information under this heading pertains only to the MGC 100. 1.5 Measuring Ranges Measurement Range / Resolution N2O (MGC 100)*....................................................... 40 to 100% / 0.
MGC 100/200 2.0 OPERATION 2.1 Important Note Always ensure that the instrument’s gas outlet (Figure 1, Item B) is unobstructed and open to the atmosphere. 2.2 Switching the Instrument ON/OFF Switch ON the instrument by momentarily pressing the button (Figure 1, Item F). Switch the instrument OFF by pressing the button for at least 3 seconds, or until the display goes blank.
MGC 100/200 2.3 Connecting Instrument to Medical Gas Outlet Before proceeding, turn ON the instrument and allow it warm-up per Section 2.2. The pump should be OFF at this time. After warming up, connect the instrument’s gas inlet through the supplied flow restrictor to the medical gas outlet as follows: CAUTION: Never apply gas directly from the medical gas outlet to the instrument, as internal damage to the instrument can result.
MGC 100/200 2.4 Starting and Ending a Test With the instrument turned ON and connected to the medical gas outlet per Sections 2.2 and 2.3, begin testing with the pump OFF. Read the display as described in Sections 2.5 and 2.6. After completing a test, disconnect the sample tubing from the gas outlet. Purge out any residual gas by first disconnecting the flow restrictor, and then turning ON the pump by momentarily pressing the button.
MGC 100/200 Activate the peak-reading mode by pressing and holding the f3 button for 3 seconds. Once in the peak-reading mode, toggle the display between “peak CO2” and “peak CO” by momemtarily pressing the f3 button. peakCO2 1,530 f3 peakCO 200 To return the instrument to its current-reading mode, again press and hold the f3 button for 3 seconds. To reset the peak gas readings back to the current readings, switch the instrument OFF and then back ON. 2.
MGC 100/200 2.7.2 MGC 200 – Snapshot & Data-Logging After obtaining a steady reading, momentarily press the f1 button to store (take a snapshot of) the reading shown on the display along with the current time and date. Pressing and holding down the f1 button for at least 3 seconds starts continuous data logging of the readings at a preset interval (factory set at 15 minutes). To stop data-logging, momentarily press the f1 button.
MGC 100/200 2.10 Fault Condition Warning Both instruments are capable of alerting the operator of an internal fault condition (i.e., a sensor failure or blockage in the infrared path). If a fault occurs, the instrument’s beeper will sound continuously, and the following message is displayed until the instrument is switched OFF. FAULT If the fault warning is displayed at any time, then the instrument must be returned to Bacharach for evaluation. 2.
MGC 100/200 3.0 MAINTENANCE 3.1 Cleaning Keep the instrument clean by wiping it with a soft cloth dampened with a mild detergent solution. 3.2 Sunlight The unit should not be left out in direct sunlight, or in other areas where excessive heat exists, for long periods since component damage due to overheating may result. 3.3 Servicing There are no user-serviceable parts inside the instrument. Unauthorized disassembly of the unit will invalidate the warranty. 3.
MGC 100/200 Release the f2 button and zero the gas sensor(s) as described in either Section 3.7 or 3.8. WARNING! Failure to zero the sensor(s) after resetting the instrument to its factory settings may cause incorrect gas readings to be displayed. 3.6 Battery Charging When the “BattLow” message is displayed (refer to Section 2.8), the instrument must be recharged using the supplied battery charger.
MGC 100/200 3.7 Zeroing the N2O Sensor (MGC 100) Zero the N2O sensor of the MGC 100 as follows: 1. Turn ON the instrument and allow it to warm up per Section 2.2. 2. With the instrument sampling fresh air, turn ON the pump by momentarily pressing the button and allow the pump to run to purge out any resident gas. Then turn OFF the pump once a steady reading is obtained (approx. 60 seconds). WARNING! It is essential that the instrument is in fresh air before attempting to zero the sensor.
MGC 100/200 3.8 Zeroing the CO2 & CO Sensors (MGC 200) Zero both the CO2 and CO sensors of the MGC 200 as follows: 1. Turn ON the instrument and allow it to warm up per Section 2.2. 2. With the instrument sampling fresh air, turn ON the pump by momentarily pressing the button and allow the pump to run to purge out any resident gas. Then turn OFF the pump once a steady reading is obtained (approx. 60 seconds).
MGC 100/200 3.9 Span Calibration (MGC 100) A span calibration of the MGC 100 consists of flowing a recommended certified calibration gas of 99.5% N2O (customer supplied) through the instrument and calibrating the instrument to the applied gas level. WARNING! If using a gas concentration other than 99.5%, the instrument’s default span gas value must be changed to match the applied gas using the optional BACH-COM software; otherwise, inaccurate gas readings will result.
MGC 100/200 3. Press and hold down the f2 button until the following displays appear. Note that the instrument beeps 5 times when it enters the User Cal mode, and then emits a steady tone indicating that the f2 button can now be released. User Cal f1-> Air f3-> Gas An operator can abort this procedure by momentarily pressing the f2 button. 4. To calibrate the instrument using span gas, press the f3 button. The following display will appear. f1> 99.5 0.
