5.8 Duty Cycle Parameter Specifications

“Sleep Time”: How long is the average or fixed period

the attached system is in sleep mode with much re-

duced power consumption? Any period length must

be entered in milliseconds.

Note: This must not include the active period’s duration.

“Sleep Power”: What is the power consumption during

the sleep period? Refer to the field caption for re-

quired units.

“Active Time”: How long is the average or fixed active

period the attached system is active, doing sensing

computing or radio transmission? Any period length

must be entered in milliseconds.

Note: This value must not include the sleep period.

“Active Power”: What is the power consumption dur-

ing the active period? Since power consumption varies

with the tasks carried out during the active period,

each specific portion should be accumulated and aver-

aged over the entire active period. The resulting value

is entered into this field. Refer to the field caption for

required units.

Checking “Connect load” virtually connects the load to

the thermogenerator. With a positive energy balance,

the battery continues to be charged (green level indi-

cator) while a negative energy balance discharges the

battery (red level indicator).

“Power balance” is always calculated and updated

during active connection to an attached TE-CORE /RF.

However, the charge level color indication only works

with “Connect load” being checked
