Batteries and Chargers
Options:
The following options will cause excessive current draw:
•
Modem, if left enabled.
•
Alarm Relays
•
4 to 20 mA outputs
•
Analog Channels (If using 12 V dc internal supply)
Recording Channels:
Each channel added to the recording interval, adds additional awake time to the interval.
Optimum recording is obtained logging two channels or less.
Downloading from the Data Transfer Unit:
The frequency at which the meter gets downloaded will also affect battery life. During an
RS232 download to a Data Transfer Unit, the meter must power up to retrieve the data
from memory, and also power the Data Transfer Unit. Download data only once per week
or less when possible.
Selection of Batteries:
Using the wrong batteries in the Alkaline Battery Pack will result in less than expected
battery life and could possibly damage the assembly.
The LED indicator located above each charging station functions differently, depending
on the type of battery being charged.
