There are two user-defined parameters at the bottom of the window. At first, they
will be listed as a question mark “
?
”. These parameters allow you to monitor a
range of harmonics for voltage, current or power.
To activate these parameters:
- Select the
?
line you want to modify using the
▲ and ▼
buttons, then
press the
button to confirm.
- Next use the
▲ and ▼
buttons to scroll through the available choices
(
Uh
,
Vh
,
Ah
, and
VAh)
, then press
.
- Use the
► button to move to the first modifiable field for this parameter.
A value from 00 to 50 may be selected using the
▲ and ▼
buttons.
Press the button to select the value.
- Press the
►
button to move to the upper value. Use the same process
to select the upper limit.
- Press the
►
button again to move to the right to modify the last value
needed to complete the definition. Here you will choose whether to
include all harmonics or only the odd harmonics.
- Use the
▲ and ▼
buttons to make this selection. The diamond preced-
ing the
Odd Only
choice will appear filled in for selected and unfilled
for not selected.
Example of a user defined choice:
Vh 02 → 15
Odd Only.
In this user defined condition, all odd voltage harmonics between the 2
nd
and the
15
th
will be recorded.
• Press the button when you have finished selecting all the parameters to be
recorded to apply the new setup.
The battery may fully discharge when recording for long periods of time
while not connected to a power supply. The Model 8335 will continue to
record for some time, even if below the minimum battery charge value.
However, the display may not come back on, and will eventually stop
saving data when the battery is too low. All data recorded will be saved.
If in the Record Mode, and the display does not come ON, do not turn the
instrument OFF. Supply power to the Model 8335 with the power cord and the
display will come back ON when any button (other than ON/OFF) is pressed.
