This command may be password-protected. Toaccess this command:
•If the SYST:PASS:CONV? command returns a 0 (probe password-protec-
tion is disabled), the password is not required.
•If the SYST:PASS:CONV? command returns a 1 (probe password-protec-
tion is enabled), the password must be successfully entered using the
SYST:PASS:CEN<pass> command (see Section 9.4.11, Password Com-
mands).
8.4.4.11 CALCulate<chn>:CONVert:TEST? <res>|<volt>
Teststhe temperature conversion for the specified channel.
CALC2:CONV:TEST?100.0145
0.0100
The CALCulatesuffix, <chn>, specifiesthe channel (1 to 4) or memory chan-
nel (5 to 14). ForPRT/Thermistor channels, the <res> parameter specifies a re-
sistance valueto convert to temperature. The <res> parameter is always in
Ohms for PRTsand KOhms for Thermistors. For Thermocouple channels, the
<volt>p arameter specifiesa voltage value to convert to temperature. The
<volt>parameter is always in mV. The response to this command is a tempera-
ture in the currently selected units. The current system units determine the scale
of the response.
8.4.5 Calibration Coefficient Commands
The calibration coefficientcommands are used fo r querying and setting the
channel calibration date, due date, linearity,offset, scale, and RJC.
8.4.5.1 CALibrate:AUTo
Executesth e automatic calibration procedure when using Fast Measurement
Mode (see Sections6.9, Fast Measurement Mode, 7.1.1, Measure Period and
FastMeasurement Mode, and 7.1.5, Display Functions/Auto-Cal).
CAL:AUT
8.4.5.2 CALibrate<chn>:DATE:CALibrate? [MIN|MAX|DEF]
Returns the calibration date for the specified channel.
CAL1:DATE:CAL?
2000,9,22
The CALibratesuffix, <chn>, specifies the channel (1 to 4). This command
does notapply to memory channels. The response is returned in the format,
<year>,<month>,<day>. Specifying theMIN parameter returnsa value of
