|
Read the calibration procedure before calibrating. Improper calibration can reduce accuracy and reliability. |
Performs a low-level calibration of the ADC (analog-to-digital converter) circuitry.
|
You must unsecure the instrument to calibrate it or to change the calibration code or security code. |
Parameter | Typical Return |
---|---|
(none) | 0 (successful) or 1 (unsuccessful) |
Calibrate the ADC:
CAL:ADC? |
Performs a calibration using the calibration value based on the function and range (CALibration:VALue). A short must be applied for the resistance and voltage measurement functions, and the inputs must be open for the current measurement functions.
|
You must unsecure the instrument to calibrate it or to change the calibration code or security code. |
Parameter | Typical Return |
---|---|
(none) | +0 (pass) or +1 (fail) |
Perform a zero calibration of the ACV measurement function and return a pass/fail indication: CONF:VOLT:AC CAL:SEC:STAT OFF,MY_CAL_CODE CAL:VAL 0.0 CAL? CAL:STOR CAL:SEC:STAT ON |
Returns the calibration count. Read and record the initial count when you first receive your instrument.
Parameter | Typical Return |
---|---|
(none) | +117 |
Return the calibration count: CAL:COUN? |
Returns the date of the last calibration in the format yyyy,mm,dd.
Parameter | Typical Return |
---|---|
(none) | 2014,4,26 |
Return the calibration date: CAL:DATE? |
Sets the security code (calibration password) to prevent unauthorized calibrations.
|
You must unsecure the instrument to calibrate it or to change the calibration code or security code. |
Parameter | Typical Return |
---|---|
Unquoted string up to 12 characters Must start with letter (A-Z) May contain letters, numbers (0-9) and underscores |
(none) |
Set new security code (calibration password): CAL:SEC:STAT OFF,OLD_CAL_CODE CAL:SEC:CODE TST_DUT165 CAL:SEC:STAT ON |
Unsecures or secures the instrument for calibration.
|
You must unsecure the instrument to calibrate it or to change the calibration code or security code. |
Parameter | Typical Return |
---|---|
{ON|1|OFF|0}. Default: ON. | 0 (OFF) or 1 (ON) |
Unsecure calibration: Secure calibration: |
Takes calibration constants in volatile memory (CALibration:ALL?), and places them in nonvolatile memory, where they are not changed by cycling power, *RST, or SYSTem:PRESet. Do this at the end of calibration to avoid losing changes.
|
You must unsecure the instrument to calibrate it or to change the calibration code or security code. |
Parameter | Typical Return |
---|---|
(none) | (none) |
Store calibration constants into non-volatile memory: |
Stores a message in calibration memory. Common messages include the last calibration date, calibration due date, or calibration department contact information. You can perform this query regardless of whether the instrument is secured.
|
You must unsecure the instrument to calibrate it or to change the calibration code or security code. |
Parameter | Typical Return |
---|---|
Quoted string up to 40 characters May contain letters, numbers, spaces, and other common characters. |
"FOR CAL HELP, CALL JOE AT EXT 1234" (If no string stored, returns "") |
CAL:STR "FOR CAL HELP, CALL JOE AT EXT 1234" |
Returns the temperature of the last calibration in °C.
Parameter | Typical Return |
---|---|
(none) | +2.42850208E+001 |
Return the calibration temperature: CAL:TEMP? |
Returns the amount of time since the last calibration in the format hh,mm,ss.sss.
Parameter | Typical Return |
---|---|
(none) | 20,15,30.000 |
Return the calibration time: CAL:TIME? |
Specifies the value of the applied calibration signal.
|
You must unsecure the instrument to calibrate it or to change the calibration code or security code. |
Parameter | Typical Return |
---|---|
Numeric, default 0.0 | +2.37000000E-02 |
Specify calibration value 0.0237: |
