!
Note!
1. You can also perform calibration by means of the QUICK SETUP menu. → See Page 96 ff,
table 3: QUICK SETUP menu.
2. Using the FLOW-MEAS. TYPE parameter, you can choose between the following flow types:
– Volume p. cond. (volume under operating conditions)
– Gas norm. cond. (norm volume under norm conditions in Europe: 1013.25 mbar and
273.15 K (0 °C))
– Gas std. cond. (standard volume under standard conditions in USA: 1013.25 mbar (14.7 psi)
and 288. 15 K (15 °C/59 °F))
– Mass p. cond. (mass under operating conditions)
3. Depending on the flow type selected, you can choose between various units. You can also
specify a customer-specific unit.
See parameter description for PRESS. ENG. UNIT (→ Page 126), UNIT FLOW (→ Page 127),
NORM FLOW UNIT (→ Page 127), STD. FLOW UNIT (→ Page 127) and MASS FLOW UNIT
(→ Page 128).
4. In the lower measuring range, small flow quantities (creepages) can lead to large measured
value fluctuations. You can activate low flow cut-off via the LOW FLOW CUT-OFF parameter
(→ Page 130).
