8.2.2 Setting Calibration Data
To set calibration data, press the [*] key in the measurement mode, (when password is selected,
enter the password (XXX), ) and select the parameter [*CAL.DT]. See Figure 5.4 for the process
at the setting level.
(a) Zero-point density [*Z_DNS]
Configurable range : 0.0000 to 6.0000 (kg/m 3 )
0.00000 to 0.40000 (lb/ft 3 )
(b) Span-point density [*S_DNS]
Configurable range : 0.0000 to 6.0000 (kg/m 3 )
0.00000 to 0.40000 (lb/ft 3 )
(c) Output hold value during calibration [*C_HLD]
• Disable:
0
• Enable: 1
• Enable (preset value): 2
(d) Setting of preset value [*PR.SET]
Configurable range: -10.0 to 110.0
(Applies only if item (c) above is set to “2”.)

*2: Set a value using the [ ], [ ] and [ENT] keys.
If you enter a value that exceeds the limits, the display shows [*OVER].
Press the [YES] or [NO] key to re-set the value.
*3: This step is skipped if the parameter [*C_HLD] is set to a value other than "2".
