Chapter 5 Error Messages Calibration Errors Invalid secure code An invalid calibration security code was received when attempting to unsecure or secure the multimeter. Example The program configures the multimeter for dc voltage measurements.

Don’t show me this message again. Refer to the Service Guide for more information. Input buffer overflow Output buffer overflow Insufficient memory You can use the following commands to make min-max measurements.

There are five math operations available, only one of which can be enabled at a time. Crest factor errors for the HP A are shown in the specifications in chapter 8.

The threshold resistance is adjustable hp344011a from the front panel. To read the minimum, maximum, average, and count, use the MATH menu. Errors In High Resistance Measurements You may never have to change any of the measurement parameters discussed here, but they are provided to give you the flexibility you might need.

See the next page if you need to replace the power-line fuse. The multimeter clears the value when min-max is turned on, when power has been off, or after a remote interface reset.

Calibration was referenced to measurement results of my Keithley which was calibrated in February by Tektronix, and is most accurate meter I currently have up to date Few photos of calibration steps for better understanding. Error Messages Errors are retrieved in first-in-first-out order. Remove the carrying handle, and the front and rear rubber bumpers, before rack-mounting the multimeter.


Notice that the position of the decimal point changes and the displayed number increases by a factor of This may be useful in applications where you want to allow the input to settle before taking a reading, or for pacing a burst of readings. It is also assumed that manual ranging is enabled to ensure proper full scale range selection.

To Measure Voltage Chapter 3 Features And Functions Each math operation performs a mathematical operation on each reading or stores data on a series of readings. To Make Dbm Measurements Number Of Samples Chapter 3 Features and Functions Triggering Number of Samples Normally, the multimeter takes one reading or sample each time it receives a trigger from the selected trigger source if the multimeter is in the wait-for-trigger state.

Set the resolution to 6 digits you can use the 6 digits slow mode for further noise reduction. You can, however, instruct the multimeter to accept multiple triggers. For 2-wire ohms, the voltage drop across the resistor being measured is sensed internal to the multimeter. Each error FIFO string may contain up to 80 characters.

Even if the cable has the proper connectors for your system, the internal wiring may not be correct. These are often a problem on old instruments, if contacts got contamination and unable to maintain low resistance connections.

To adjust the reading hold sensitivity band, use the TRIG menu. Display Control Chapter 3 Features and Functions System-Related Operations Display Control To speed up your measurement rate, or for security reasons, you may want to turn off the front-panel display.

Verify that you have connected the correct interface cable and adapters. Trig Multimeter is waiting for a single trigger or external trigger.

Selects a higher range and Man annunciator is on when disables autoranging. Chapter 8 Specifications To reduce the effects of measurement loading errors, you can set the input resistance to greater than 10 G for the mVdc, 1 Vdc, and 10 Vdc ranges. This limited test assures you that the hp34401a is operational.

To Make Null relative Measurements Chapter 6 Application Programs Application Programs Mznual first FIFO error returned is the first error that was stored. Page Chapter 5 Error Messages Execution Errors Program mnemonic too long A command header was received which contained more than the maximum 12 characters allowed.

Chapter 4 Remote Interface Reference Simplified Programming Overview If you send two query commands without reading the response from the C a u t i o n first, and then attempt to read the second response, you may receive some data from the first response followed by the complete second response. To Set The Hp-ib Address In manal example, you will turn off the front-panel beeper. They are not included in the LM is socketed, just like more recent xA instruments.

Multimeter is in remote mode remote interface. This section explains these errors and shows how to apply them to your measurements.
