3.12 ERROR MESSAGES AND STATUS CODES
The following tables show the various error, warning or status messages that may appear from time to time, along with
an explanation of the meaning of the message. In some cases, the messages may be ignored, while other messages
indicate a major malfunction or error that prevents the power meter from performing measurements.
Table 3-6. Graph/Text Header Error and Status Messages
These messages may appear in the Header at the top of the display in Graph or Text mode.
NoSensor
There is no sensor present on this channel.
SnsrCalT
The sensor’s (internal EEPROM) cal factor tables are invalid.
AutoCal
The peak sensor’s serial/model number does not match the previous device that
was auto-calibrated on this channel. A new AutoCal is needed.
InstrCal
The DSP cal table for this peak sensor is not initialized. An AutoCal is needed.
TmpDrift
The temperature of the peak sensor has drifted by more than 4 degrees C from
the temperature at which the sensor was AutoCaled. For best measurement
accuracy, a new auto-calibration should be performed.
Meas Off
The measurement mode (or display mode) for this channel is turned off.
Table 3-7. Sensor and Probe Error Messages
These messages may appear briefly on the main display when a sensor or probe is plugged-in.
Page Error: nnnnnnnn
One or more of the sensor’s internal EEPROM tables contains a checksum error.
*No Calib. Tables*
No peak sensor calibration tables have been saved. A new auto-cal is needed
before measurements can be made.
*AutoCal Required*
The peak sensor’s serial and model number do not match the sensor for which
calibration tables have been saved. A new auto-cal is needed before measure-
ments can be made.
*Using Default Cal*
The CW sensor’s serial and model number do not match the sensor for which
the zero or fixed-cal factors were last performed. Default values will be used
until a zero and fixed-cal or AutoCal are done for this sensor.
