Power Supply & Battery Charging
The internal battery of the J2K base is a 6 V; 7,2 Ah lead acid battery. Full capacity is achieved with
a 8-12 hour charge and will operate the analyzer for up to 6 hours, under most conditions. In order
for the Peltier Gas Cooler to work at maximum efficiency, it is necessary to operate on 120 VAC
power. The analyzer may be stored while connected to AC current. Once the internal battery is fully
charged, it will switch to a trickle charge to maintain maximum capacity.
The batteries in both the base and the remote should be recharged when the instrument displays a
"Low Battery" warning. Battery voltages can be checked by viewing the "CONTROL" screen on the
remote display. The low battery warning in the base unit is activated when the charge drops below 6
V. At 5.8 V, the analyzer will not operate on the batteries, but can be powered by AC power. The
low battery warning in the remote unit is activated when the charge drops below 4 V. At 3.8 V, the
remote will not operate on the batteries, and must be recharged in the base. However, it will operate
in the base unit cradle, while it is re-charging.
The control module of the ecom-J2K is powered by 3 nickel-metal-hydride batteries, (type AA).
When these batteries need charging, they can be recharged by docking the control module to the
base unit.
2 different charging options are available:
(
Adjustments / Internal / Reloading function / <OK>
):
1. Recharging function ON (<F1> = YES):
- batteries slowly and deeply recharged
- recommended if analyzer used frequently
2. Recharging function OFF (<F4> = NO):
- provides quick charge
- recommended if analyzer used infrequently,
or for emergency situations
Never use alkaline batteries to operate the control module of the ecom-J2K!
