MANUAL DATA INPUT
1. Connect the Datalogger to the meter using the
double earphone jack cable. Plug one end into
the “RS232 Out” socket on the meter source.
Plug the other end into the “uP IN” socket on
the datalogger. (DMM sockets are for use with
future products) Do not turn on the meter
until the datalogger is ready for input.
2. Slide the ““AUTO/MAN/OUT” switch (Fig.1-6)
to the “MAN” position and turn the power on.
The “FULL” indicator illuminates when the
datalogger is turned on after changing the
batteries. This must be cleared (reset)
before data can be logged into the
datalogger. See Item 7.
3. Press the “PAUSE” button (Fig.1-10.) This will
save one data point to memory. The “DATA”
light will flash with each point added.
4. Continue pressing “PAUSE” to collect
additional data points. In manual input mode,
the “Sampling Interval Time” settings are
invalid.
5. Reset or Memory Clear– With the datalogger
set to “PAUSE”, press the “RESET” button
(Fig.1-9) for a minimum of 4 seconds until the
display shows “00”. This will completely clear
all data in memory.
6. Memory Full Indicator– When the memory is
full (7999 data points), the “FULL” light (Fig.1-
2) will be on. You must clear the memory and
the “FULL” light will go off.
