Putting it all Together (Monitoring for the First Time)
This section is intended to insure that you will be successful in your first (and later) monitoring attempts.
There are several ways to start monitoring. If you wish to use the default values, simply turn the unit
on, press [Monitoring On/Off], then [Yes/Accept] (to indicate that you wish to start monitoring),
[No/Reject] (to indicate you do not want to combine the new log with the existing log inside the unit),
and then [Yes/Accept] (to affirm that you want to erase the old log in the unit). Monitoring will then
begin and continue until you stop it or turn the meter off.
The remainder of this chapter assumes that you wish to use the computer to customize or at least
check your monitoring settings prior to starting monitoring. The computer must be running the ATPOL
II Manager (PSM) software that comes with the meter and the computer must be connected to the
ATPOL II using the communications cable that comes with the meter.
There are three ways to start logging. ATPOL II can start immediately by command of PSM, can start
at a time and date set by PSM, or can start when turned on and connected to power. If you wish PSM
to command ATPOL II to start logging, then you must have the computer with you when you connect
ATPOL II up for logging. The other methods can be set up at another time and location and then
ATPOL II can be transported to the site of logging.
The first step is to set up or check the parameters for logging.
1. Review the chapter
to ensure that Bluetooth communications are
established between the PC operating system and the meter after the meter is turned on.
2. Enter PSM and note that PSM has successfully connected to ATPOL II. This will be clear by the
box on the main menu with the words “Unit Connected” appearing within a large green banner.
Note that the box also says “Serial Comm: enabled” and “Datalogging: enabled”.
3.
Click on “Data Setup” and review the setup that is in ATPOL II. Review the chapter on
Setting the Swell/Dip Trigger Threshold
,
Setting the
Transient Trigger Thresholds
, and
Allocating Memory within ATPOL II
and make any changes that
are needed in the data setup and store it to ATPOL II and perhaps save it to a file. For instance,
check to see how many records and waveforms can be recorded, given the choice of variables and
allocation of memory, and check the length of time that logging can proceed before the log will fill
up. If any of these items is too small, remove unneeded variables, change the logging period, or
reallocate memory. As you change the variables or logging period, you will see the capacity of the
log (in number of records and in recording time) change to reflect the change. If you care about
consumption logging, make sure the logging period is short enough to have at least 10 records in
the log before you end logging. Less than 10 records will not look presentable when graphed.
Generally, strive to have at least 100 records in a consumption log. That would allow for 10 data
points in each column of the graph.
When ATPOL II is at the site where it will be used:
1. Hook up the voltage leads and current probes to the circuit being monitored referring to the
2. Insert the power plug into the 12VDC jack on the right side of the meter as described in the
section. Power for the meter will come from a wall charger or from a line-to-
DC converter. If you have a line-to-DC converter accessory, attach its leads as shown in the
Connecting to Line-To-DC (LDC) Converter Accessory
section. If you are going to monitor just a
few hours and the meter’s internal battery is fully charged, you can skip this step.
