.4.3 Making the Settings of Temperature Measurement
NOTE
The settings of the waveform display color, waveform display graph type,
magnification/compression ratio along the measurement range, zero position
and low-pass filter are the same as in the 8936 ANALOG UNIT.
Setting the measurement range and drift compensation
Set the measurement range.
Drift compensation is a function that periodically (about once per second)
cancels the variances in the reference voltage that accumulate over time.
Method Screen: CHANNEL 1
1. Call up the CHANNEL 1 or DISPLAY screen.
2. Move the flashing cursor to the point shown
in the figure on the left.
3. Use the function keys, the
RANGE key or
the JOG control to make the selection.
: Move the cursor up in the selection window.
: Move the cursor down in the selection
window.
4. Set drift compensation.
Drift compensation can be used with
temperature measurement.
: Drift compensation is enabled.
: Drift compensation is disabled.
・Upon resetting the system, the "Input Selection" item is set to Voltage.
・If ambient temperature changes suddenly, loss of thermal equilibrium can
result in measurement error. When this occurs, allow the unit to acclimate
to the new temperature for about one hour, then take measurements after
thermal equilibrium is reached.
・It is recommended that drift compensation be turned ON when using a
thermocouple with small thermoelectromotive force (sensor R, S or B) to
record over an extended period of time in an environment where ambient
temperature fluctuates.
・If the temperature input terminal is exposed to a strong draft, loss of
thermal equilibrium at the input may result in measurement error. When
taking measurements under such conditions, arrange the unit in such a
manner that the input terminal is protected for direct exposure to drafts.
