Step 1: Press the
key while simultaneously holding down the
key. The LCD shows
.
Step 2: Pressing the highest-order
key causes the LCD to show
.
Step 3: Pressing the
key enters the measurement CAL mode.
The
indicator blinks on the LCD and the
symbol
appears. The calibrator is now ready for defining the CAL 0
setpoints of measurement functions.
Step 4: Using the function selector switch, select the range to be ad-
justed.
Step 5: Pressing the
key confirms the CAL 0 adjustment setpoint.
The CAL indicator on the LCD changes to
, setting the cali-
brator ready for full-scale calibration.
Step 6: Apply the CAL FS adjustment setpoint input of each range in
Table 10.2 from the calibration standard to the H and L input
terminals of the calibrator.
Step 7: Pressing the
key confirms the CAL FS adjustment
setpoint. At this point, the 0 and FS symbol blinks.
Step 8: Pressing the
once again saves the adjustment setpoint in
memory.
NOTE
• Range adjustments are made automatically within the calibrator so that the
LCD reading matches the adjustment setpoint in question given in the table
with reference to the input applied as described above. Therefore, you need
not make any range adjustment with
and
keys.
• Saving the adjustment setpoint results in the overwriting of existing data.
Be extremely careful since the previous adjustment setpoints are cleared.
• The temperature measuring ranges of the RTD function are adjusted at the
same time when the 400
Ω
range is adjusted.
