Warm-Up And Offset Voltage Adjustment - YOKOGAWA 701925 PBDH0500 User Manual

3. Operating Procedure

Warm-up and Offset Voltage Adjustment

Warm-up
Immediately after connecting the probe, the heat emitted by the probe
itself causes the offset voltage to drift. After turning on the power, warm
up the probe for at least 30 minutes to stabilize it.
Offset Voltage Adjustment
Do not apply excessive force to the offset voltage adjustment
screw. Doing so may damage the internal variable resistor.
French
N'appliquez pas une force excessive sur la vis de réglage de la
tension de décalage. Cela pourrait endommager le résistance
variable interne.
Adjust the residual offset voltage that remains even after warm-up. Turn
the offset voltage adjustment screw on the probe interface unit by using
an appropriate adjustment screwdriver (see the description provided
earlier).
Note
• The offset voltage drifts depending on the ambient temperature.
Pay attention to changes in the ambient temperature when making
continuous measurements.
• Only use the offset voltage adjustment screw to adjust the residual
offset voltage. If you deliberately change the offset voltage for some
other purpose, the probe may no longer meet the specifications.
