Step 4: Conform that the
symbol is appearing on the LCD.
Step 5: Read the calibrator output on the calibration standard. Then,
using the lowest-order pair of
and
keys, adjust the read-
ing so that it matches the given CAL 0 adjustment setpoint in
Table 10.1. In the CAL mode, the lowest-order pair of
and
keys are used to increase or decrease the least-significant
two digits, including the auxiliary digit. Adjust the value mea-
sured with the calibration standard to the given adjustment
setpoint in Table 10.1.
Step 6: Press the
key to confirm the CAL 0 adjustment setpoint.
The CAL indicator on the LCD changes to
, setting the cali-
brator ready for full-scale adjustment.
Step 7: Using the lowest-order pair of
and
keys, adjust the
reading of the calibration standard so that it matches the
given CAL FS adjustment setpoint in Table 10.1.
Step 8: Press the
key to confirm the CAL
FS adjustment setpoint. The 0 and FS
symbols on the LCD blink.
Step 9: Pressing the
once again saves the
adjustment setpoint in memory.
Step 10: The 0 and FS symbols stop blinking, causing the calibrator to
return to the state discussed in step 4. Using the function
selector switch, select the next range. By repeating steps 4 to
9, you can adjust the source function assigned to that range.
NOTE
• Saving to memory results in the overwriting of existing data. Be extremely
careful since the previous adjustment setpoints are cleared.
• Both the thermocouple and RTD ranges are adjusted at the same time when
the 100 mV and 400
Ω
ranges are adjusted.
