User’s Manual GMH 3151 H61.0.02.6C-08 page 9 of 16 7.4 Averaging Function The averaging function concerns the display values (LCD and interface). It is completely independent from the averaging of the logger function, please don’t mix them up! The averaging integrates the measuring values during a selectable period of time and then calculates the average display value.
User’s Manual GMH 3151 H61.0.02.6C-08 page 10 of 16 8 Operation Of Logger The device supports two different logger functions: each time when „store“ (key 6) is pressed a measurement will be recorded. „Func-Stor“: „Func-CYCL“: measurements will automatically be recorded each interval, which was set in the logger menu ‚CYCL‘...
User’s Manual GMH 3151 H61.0.02.6C-08 page 11 of 16 8.2 „Func-CYCL“: Automatic Recording With Selectable Logger-Cycle-Time The Logger-Cycle-Time is settable (p.r.t. Configuration). For example „CYCL“ = 60: A measuring is recorded after each 60 seconds. When the slow measurement "rAtE-Slo" is chosen, additionally a low power function is available: „Lo.Po“.
User’s Manual GMH 3151 H61.0.02.6C-08 page 12 of 16 9 Output The output can be used as serial interface (for USB 3100, USB 3100 N, GRS 3100 or GRS 3105 interface adapters) or as analog output (0-1V). If none of both is needed, we suggest to switch the output off, because battery life then is extended.
User’s Manual GMH 3151 H61.0.02.6C-08 page 13 of 16 9.2 Analogue Output – Scaling with DAC.0 and DAC.1 Note: Analogue output can not be used during logger recordings With the DAC.0 and DAC.1 values the output can be rapidly scaled to your efforts.
User’s Manual GMH 3151 H61.0.02.6C-08 page 14 of 16 For measurements of under pressure: (with higher negative measuring range) Connect plastic tube with internal diameter of 4 mm to pressure port "B". Port "A" will not be used! Pressure sensors GMSD 2,5 MR, GMSD 25 MR and GMSD 350 MR allow for measurements of under pressure up to the entire over pressure measuring range by re-plugging the tube to pressure port "A".
