Power supply The instrument must be charged in a safe area using the 100-240 V charger supplied. The unit is not designed to operate from mains power
Note

The 5100 i.s is suitable for operation in hazardous areas only when powered by the internal battery. The power supply must only be used to charge the internal rechargeable battery when in a safe area.
Lithium-ion batteries have no 'memory effects', so they can be recharged from any charge level, for any duration, and as often as preferred without affecting service life.
To ensure optimum service life of the battery, we recommend:

  • recharging the battery after each session of operation
  • when not in use, storing (with fully charged battery) in a cool environment and recharging every 2 months
* Sample gases containing levels of oxygen in excess of 21 % must not be measured in a hazardous area, for further information please contact Servomex offÏce
