10.3.2 Adjusting AC Voltage and Resistance
(400 Ω) Ranges
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
adjusted.
Step 5:
Pressing the
key confirms the CAL 0 adjustment setpoint.
The
CAL
indicator on the LCD changes to ,
setting the calibrator 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.
