Pressure units
The instrument is factory congured to display "PSI". Using the ▲ and ▼ keys (ZERO
and MAX/MIN) you can scroll up and down through the 18 engineering units dened as a
standard, and through the user-dened units or scale. Once the required measuring unit
is displayed, press the Enter key or the CONFIG key. The pressure will then be displayed
in the selected engineering units. A list of available engineering units is given in chapter
3 "Specications", of this manual. Details on the conguration of user-dened measuring
units is given in chapter 6.3 "Supervisor mode".
Automatic Power-o
The function for automatic shut-down can be set in intervals of 1 minute, from 1 to
30 minutes, or it can be turned o (continuous operation). The measuring instrument is
delivered with an automatic power-o after 30 minutes. Dene the required interval using
the ▲ and ▼ keys. The OFF setting is at the very start of the options before setting for
1 minute.
Displaying battery voltage
The current battery voltage, and the remaining useful life of the battery, are displayed in the
form of a progress bar display.
Indication of the current temperature
The measuring instrument is temperature compensated. This option displays the tempera-
ture measured by the internal sensor. The display value can be switched from degrees
Fahrenheit to degrees Celsius.
Setting damping
Using the ▲ and ▼ keys you can turn this option on and o. With damping enabled, the
measured values from pulsating pressure sources are smoothed.
Conguring the sampling rate
The sampling rate denes the frequency with which the pressure is measured and the
indication is refreshed. The options are 0.5, 1, 3 and 10 measurements per second. The
shortest response time is 10 measurements per second.
TARE (setting Tare)
Using this option you can set the constant oset value which will be subtracted from the
measured pressure. If, for example, TARE is set to 30 bar and the measured pressure is
37 bar, the measured value displayed will be 7 bar. A pressure of 27 bar would then be
displayed as -3 bar. The TARE value is set manually using the ▲ and ▼ keys, it depends on
the engineering units and the resolution selected for the indication. The TARE value can be
set to the maximum scale range. The progress bar indication always indicates the actual
pressure in relation to the entire measuring range, irrespective of the Tare setting. This is
performed for safety reasons so that when "0" is displayed, it can still be shown that there
is a corresponding pressure at the pressure gauge.
