Introduction
Thank you for purchasing the Hioki SS7081-50 Battery Cell Voltage Generator. To obtain maximum performance from
the instrument over the long term, be sure to read this manual carefully and keep it handy for future reference.
Target audience
This manual has been written for use by individuals who use the product in question or who teach others to do so.
It is assumed that the reader possesses basic electrical knowledge (equivalent to that of someone who graduated
from the electrical program at a technical high school).
Accuracy
Hioki defines measurement accuracy in terms of percentages of the setting, the full scale, and the reading and
digits.
Setting
Set value
Indicates a value set so that the instrument can generate an output, such as voltage and
current, whose magnitude is equal to the set value.
“Percent of setting” means a percentage relative to the setting value.
Full scale
Maximum display value
Indicates the maximum display value of each measurement range. As for this instrument,
measurement ranges express maximum display values.
“Percent of full scale (% f.s.)” means a percentage relative to the maximum display value.
Reading
Displayed value
Indicates the value the instrument is presently displaying.
“Percent of reading (% rdg)” means a percentage relative to the displayed value.
Digit(s)
Resolution
“Digit(s) (dgt)” is a unit that represents the smallest change in the indication, which means the
figure one at the least significant digit, on the digital measuring instrument.
Confirming Package Contents
•When you open the package, carefully inspect the instrument to ensure that everything is in good condition, and
that no damage occurred during shipping. Carefully check the accessories and connectors. If the instrument seems
to have been damaged or does not work as specified, contact your authorized Hioki distributor or reseller.
•Store the instrument packaging material after opening the instrument. Use the original packaging when shipping the
instrument.
Confirm that these contents are provided.
