Extreme Temperature Probing

Extreme Temperature Probing
46
By constructing your own long sensor leads, you can use the
N2820/1A probes for extreme temperature probing, such as
monitoring a product in an environmental chamber. The following
two sensor lead examples provide accurate measurements:
• 6 feet of twisted-pair wire using two turns-per-inch. The DUT
should be grounded to the probe.
• 10 feet of shielded twisted-pair wire using two turns-per-inch.
Ground to the probe both the DUT and the shield.
Do not directly subject the probe amplifier, head, or cable to extreme
NOTE
temperatures. The probe's operating temperature range is 0°C to 40°C
(32°F to 104°F).
