The underlined values are the default settings. The set values are retained even after the instrument is turned o󰀨.
Measured value
display mode
Displayed item
Display 1 An item to be displayed can be selected between the
following: resistance, current, surface resistivity, volume
resistivity, and liquid volume resistivity.
Display 2 Displays the measurement voltage.
(Displays the character string [----] with the voltage value
for resistance calculation set to [EXT.V].)
Display format
EXP/UNIT
EXP Exponential notation Displays values, expressed in
exponential notation, to ve
decimal places.
(Example: 1.00000E + 16
Ω
).
UNIT Decimal notation Displays values, expressed in
decimal notation, that have six
signicant gures.
(Example: 10.0000 P
Ω
).
Function to set the
number of display
digits
The number of display digits can be set in the range from 3 to 6.
Resistance value Calculated from the measured current value and the measured
voltage value (otherwise, the measured current value and the
voltage setting value).
Resistivity
Calculated from the measured current value, the measured voltage
value, and the electrode constant (otherwise, the measured current
value, the voltage setting value, and the electrode constant).
Function of drawing
update during
measurement
Operation method Changes the timing of updating the measured value display.
Setting
ON/OFF
ON: Updates the measured value display for each
measurement.
OFF: Does not update the measured value display (The value
of VMONI will be updated regardless of this setting).
Voltage output
function
Operation method Sink and source (Supports charge and discharge)
Current limitation
direction
Current can be limited in both directions.
Voltage output value
setting
0.1 V to 1000.0 V (Setting can be changed in increments of 0.1 V)
0.1 V to 2000.0 V (the SM7120 only)
Setting for output set
to OFF
Discharge (D) or high impedance (Z)
Voltage output time Time from the START signal input to set voltage stabilization
With the discharge setting: 10 ms
With the high-impedance setting: 1 ms
When the generated voltage is changed during voltage generation:
10 ms
Setting of voltage
value for resistance
calculation
Operation details Selects the voltage value used for resistance calculation.
Function setting
VMONI (measured voltage value), MES.V (applied voltage set
value), EXT.V (voltage set value for calculation)
Voltage setting range
0.1 V to 5000.0 V
Available only when the function setting is “EXT.V” (voltage set
value for calculation).
