IMPORTANT NOTES:
•
Only use the Ion Science universal battery charger (Part Number: A-26220) provided with your instrument.
•
When received as new or after Service by Ion Science or an approved Ion Science Service Centre, your
Instrument will arrive fully charged. Do NOT recharge until the "LO BAT" symbol appears. Do not leave
connected to the AC power supply unless charging and certainly no more than 16 hours from a low battery
message.
•
Excessive charging will dramatically reduce your battery life and will mean the batteries require replacing
frequently.
•
Only store the unit in a fully charged state.
Preparing the MVI for use
It is recommended that you zero your instrument in a known 'clean environment' using fresh air.
1.
Turn the instrument ON and ensure the LO BAT indication does not appear.
• If LO BAT does appear then charge the unit for 16 hours before proceeding to next step (refer to Battery
Charging Section of this manual for further information).
2.
Allow the instrument to run until you see a stable reading
• This should happen after 3 to 4 minutes when operating in the 0 to 2000 range
• Allow 10 minutes before operating in the 0 – 200 range
3.
As soon as the reading is stable you can zero the instrument
• rotate the 'zero adjust control knob' until '000' shows on the LCD screen
4.
Fit the PTFE probe and filter
