TIME SET dial
This dial is used with the
Wh/TIME
to set the integration
time interval.
For example, if the
Wh/TIME
is set at HOUR and the time
setting dial is set to 24, integration is performed
continuously for 24 hours after the integrator
START
switch is pressed and then automatically stops.
If the dial is set to "00", the timer does not operate and
continuous integration is performed.
Data output connector ［ DATA OUTPUT ］
(Integrated watt value measurements only)
This connector is used to connect the 3171. Do not
connect any other equipment to this connector, as
applying voltage to or shorting the terminals of this
connector can cause damage.
Battery compartment
［
BATTERY BOX
］
This holds the three R6P manganese batteries used for
power backup. The batteries have a life of more than 100
hours when run continuously.
BATT shown in the lower
left corner of the power display indicates that the backup
batteries have run down. When this happens, the
batteries must be replaced immediately. (Refer to Section
7.1, "Battery Replacement.")
If the power switch is turned on while the AC plug is
disconnected, only the
INTEGRATOR
display will operate.
This indicates that the backup power batteries are
functioning normally, it is not a fault.
However,
operation without the AC plug inserted should not be
continued for any length of time, as it will run down the
backup batteries.
