How to measure the tempera-
ture of an object having ap-
plied voltage? The instrument provides this func-
tionality. Since the maximum chan-
nel-to-channel and channel-to-
ground voltage is 30 V rms AC or 60
V DC, exercise caution not to ex-
ceed those levels. When exceeding
them, take steps to prevent the volt-
age from being applied to the instru-
ment, for example by using an
ungrounded thermocouple. Precautions in “2.3
Connecting Measure-
ment Cables to the
Instrument” (p.34)
What is the maximum measur-
ing time using the battery
pack? The maximum measuring time is
about 2.5 hours (25

ue when saving data to a CF card).
When using a USB flash drive, note
that the amount of time that mea-
surement can be performed with the
battery pack may be shortened de-
pending on the USB flash drive be-
ing used.
