1.4.3 Using the Battery Eliminator and
Rechargeable Batteries
Plug the eliminator jack into the connector on the turbidimeter side.
The optional battery eliminator may be used with or without the
batteries installed. The eliminator will not charge batteries.
Rechargeable batteries may be used in the instrument, but must be
removed for recharging. See HOW TO ORDER on page 62 for ordering
information. To prolong battery life, the instrument lamp turns on
temporarily when the
READ key is pressed.

The 2100P ISO Portable Turbidimeter is calibrated with Formazin
Primary Standard at the factory and does not require recalibration
before use. See Section 2.4 on page 22 for calibration instructions.
