Specifications
Source range
Numerous ranges are available for DC voltage, DC current, resistance, temperature (thermocouple
and RTD).
Output display
Value:
5.5 digits
Polarity:
+ or –
Unit:
mV, V, mA, Ω, °C, °F
°F is available on models with the -UF suffix code.
Reference junction
compensation (RJC)
(Thermocouple
thermoelectromotive force
source)
The following three modes are available. The 2553A 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 2553A output terminals (internal).
For the accuracy specifications when RJ sensor 257875 is used and other
specifications of the 257875, see section 14.6.
Internal (INT): A correction is performed using the temperature of the 2553A output terminals
(internal).
For the specifications of the 2553A’s internal reference junction temperature
measurement accuracy and reference junction compensation errors, see section
14.1.
Manual input
(MAN):
A correction is performed using a manually input temperature. You can set the
temperature from the 2553A front panel (see section 6.5 and chapter 4). To not
apply correction, set the temperature to 0.00°C.
Selectable range: –20.00°C to +60.00°C
User definitions
Thermocouple Thermoelectromotive force corresponding to the set temperature can be sourced
according to the user-defined polynomial.
RTD
Resistance corresponding to the set temperature can be sourced according to the
user-defined polynomial.
Saving setup parameters
Saves setup parameters immediately before (approx. 1 s before) the power switch is turned off.
The next time the power is turned on, the 2553A starts with those settings.
Error log
Logs the error codes of the errors that the 2553A detects. The error log can also be displayed.
Self-test
Performs a self-test on its condition.
Initialization
Resets the 2553A to its factory default settings.
Product information display Displays the firmware version, serial number, and the like.
Communication
Communication commands can be used to remotely control the 2553A. Select the communication
interface from GP-IB, Ethernet, and USB.
Instrument protection
Trip function based on overvoltage, overcurrent, and oscillation detection are available.
