• The instrument converts measured resistance to the
resistance at a reference temperature and displays the
result.
• There are 10 compensation methods (compensation
tables) available depending on the object under test and
its characteristics. Choose the appropriate temperature
compensation table.
• The reference temperature may be set to an arbitrary
level. The selectable reference temperature ranges vary
depending on the compensation table used.
• The convertible measurement temperature ranges also
vary depending on the compensation table used.
See Appendix 4 "Temperature Compensation Table" (page 165).
4.3.1 Performing Temperature Compensa-
tion
Procedure
1. Measure temperature and insulation
resistance. The measurements are held
upon completion.
(Either may be measured first.)
3.2 "Measuring Insulation Resistance" (page 62)
See 3.4 "Measuring Temperature" (page 82).
The temperature may also be entered with
keys.
See 6.3 "Entering Temperature and Humidity
Measured with External Thermometer and
Hygrometer" (page 131).
In the step voltage test mode ([
STEP
] is on),
temperature compensation is unavailable.
Exit the step voltage test mode.
See 4.4.3 "Exiting Step Voltage Test Mode"
(page 103).
4.3 Temperature Compensation
(TC)
What is it used for?
Used to acquire insulation resis-
tance at a temperature differing from
the actual temperature at which
measurement is performed.
