indicator, Non Zero indicator, UP indicator, DOWN indicator, RJC indicator, REMOTE indicator
Sets the maximum value (MAX) and minimum value (MIN) for the output divider, deviation, and
sweep range.
Polarity cannot be set differently in the 1000 V, 10 A, 30 A, and 400 Ω ranges.
Target:
Voltage, current, resistance, temperature
Selectable range of
4 to 15
denominator m:
Selectable range of
0 to m
numerator n:
Target:
Voltage, current, resistance, temperature
Selectable range:
±20.00%
Setting method:
Two dial setting
Resolution of deviation dial 1: 0.2% of main setting
Resolution of deviation dial 2: 0.01% of main setting
5%:
The deviation is set to ±5% when the preset is selected or when the output divider n is
changed.
Preset to +5 % when increased, 5 % when decreased.
2%:
The deviation is set to ±2% when the preset is selected or when the output divider n is
changed.
Preset to +2 % when increased, 2 % when decreased.
0:
The deviation is reset to 0% when the preset is selected or when the output divider n is
changed.
OFF:
Holds the deviation. It is not preset.
Target:
Voltage, current, resistance, temperature
Speed:
Select the time for changing the setting from 0% to 100% or 100% to 0% from
approx. 8 s, approx. 16 s, approx. 32 s, and approx. 64.
The following three modes. The 2560A corrects the sourced thermoelectromotive force (RJC)
according to the selected mode.
Auto (AUTO)
If an external RJ sensor is detected, a correction is performed using the
measured temperature of the external RJ sensor.
Otherwise, a correction is performed using the temperature of the 2560A
output terminals (internal).
For the accuracy specifications when RJ sensor 257875 is used and other
specifications of the 257875, see section 16.6.
Internal (INT):
A correction is performed using the temperature of the 2560A output
terminals (internal). For the specifications of the 2560A's internal reference
junction temperature measurement accuracy and reference junction
compensation errors, see section 16.1.
Manual input
A correction is performed using a manually input temperature. Set the
(MAN):
temperature from the 2560A front panel (see section 6.6). To not apply
correction, set the temperature to 0.00°C.
Selectable range: –20.00°C to ++60.00°C
