Parameter table for the local display
Table 4: Parameter table
8.5.1
Parameter 1: Display scale
The instrument will show the measurement signal
D3 = 0 in 000...100 [%] of Range with no decimal point (default)
D3 = 1 in 04.00 … 20.00 [mA] with a fixed decimal point, 2 digits before and after the decimal point.
If the 4-20mA loop is electrically not properly connected and therefore not closed,
the display will show
OL
(open Loop) to indicate this status.
D3 = 2 in 99.99 … 9999 [mg/m3] with a floating decimal point 99.99[mg/m3] or 999.9[mg/m
3
] or
9999[mg/m
3
]
To change the display scale, follow the below procedure
Navigate to Parameter 1
Key the desired value (1, 2 or 3) into the instrument.
Safe the result by pressing K3
From now on the instrument will show the measurement result in the desired unit.
8.5.2
Parameter 2: Averaging time [sec]:
The averaging (running average) time has been adjusted to 50 seconds in the factory but can be adjusted
freely between 0 and 6000 seconds (1 h 30 min).
No.
