Calibration considerations
When performing the calibration procedures:
• Make sure that the test equipment is properly warmed up and connected to the Model
2410 fron
t panel INPUT/OUTPUT jacks. Also be certain that the front panel jacks are
selected with the TERMINALS switch.
• Always allow the source signal to settle before calibrating each point.
• Do not connect test equipment to the Model 2410 through a scanner or other switchi
ng
e
q
uipment
.
• If an error occurs during calibration, the Model 2410 will generate an appropriate error
m
essage. See Appen
dix B for more information.
WARNING The maximum comm
on-mode voltage (voltage between LO and chassis
ground) is 250V peak. Exceeding this value may cause a breakdown in in-
sulation, creating a shock hazard.
CAUTION The
maximum volt
age between INPUT/OUTPUT HI and LO or 4-WIRE
SENSE HI and LO is 1100V peak. The maximum voltage between INPUT/
OUTPUT HI and 4-WIRE SENSE HI or between INPUT/OUTPUT LO
and 4-WIRE SENSE LO is 5V. Exceeding these voltage values may result
in instrument damage.
Calibration cycle
Perform calibration at least once a year to ensure the unit meets or exceeds its specifications.
NOTE Calibration constants are stored in volatile memories of the Model 2410, which are
protected by a replaceable battery when power is off. Typical life for the battery is
approximately 10 years, but the battery should be replaced if the voltage drops
below 2.5V regardless of age. See Section 4 for battery repla
cement details.
