A common GND is used for voltage and temperature input on all
channels. Never input voltage and temperature simultaneously, since
doing so could result in damage to the sample being tested.
NOTE
・Perform the zero adjustment when measuring voltage.
・Allow the unit to warm up for at least 1 hour to ensure that the internal
temperature of the input units has stabilized (see Section 7.3).
・The voltage measurement settings are the same as in the 8936 ANALOG
UNIT.
・The digital filter can be configured when the measurement range is 1 mV to
5 mV.
・The digital filter is a function which eliminates the noise component by
additive averaging inside the amplifier. This results in a data update rate of
about 100 μs.
Setting the digital filter
Screen: CHANNEL 1, DISPLAY
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. The digital filter can be configured when the
voltage axis range is 1 mV to 5 mV.
: Digital filter is enabled.
: Digital filter is disabled.
・When using the RANGE key, the flashing
cursor can be located in any field of the
channel to be set.
・Repeat the zero adjustment when the voltage
axis range was changed, when the input unit
was changed, when the power is on/off, or
when the system is set to reset.
・When there is a sudden change in ambient
temperature, the zero position may drift. To
assure continued measurement precision,
perform the zero adjustment again.
・Digital filter settings cannot be determined
from the DISPLAY or CHANNEL 1 screen.
Check through the function key display that
appears when the flashing cursor is moved to
the measurement range item.
