INTRODUCTION The DELTA OHM DO 9704 pressure gauge and data logger has been designed for detecting pres- sure, flow rate and temperature, physical values which are very important in industrial and chemical processes.
ENGLISH 70 ON/OFF HOLD + ON/OFF HOLD ON/OFF key. Press this key repeatedly to switch the instru- ment on or off. The instrument has a cut-out system (Auto Power Off) which switches off automatically after about 8 minutes.
REL UNIT A UNIT B ENGLISH 71 KEY SIMBOLS LIT BESIDES THE NUMBERS FUNCTION DESCRIPTION The REL key allows you to display or store relative values or send them immediately onto the serial line. The values for comparison are stored at the precise moment in which the key is pressed.
A-B SERIAL OUTPUT ENGLISH 72 KEY SIMBOLS LIT BESIDES THE NUMBERS FUNCTION DESCRIPTION Pressing A-B obtains the differen- ce between the values indicated for input A minus the values of input B. The full-scale value of the two probes must be the same and they must be opera- ting with the same measure- ment units, otherwise an ERR message is given.
ENGLISH 73 KEY SIMBOLS LIT BESIDES THE NUMBERS FUNCTION DESCRIPTION P0+ + + There is therefore a limit on the minimum time that may be set as a function of the Baud Rate cho- sen: - P0 - When ENTER is pressed with P0 on the display, the instrument returns to normal operating mode without storing any parameter.
ENGLISH 74 KEY SIMBOLS LIT BESIDES THE NUMBERS FUNCTION DESCRIPTION P1+ = data dump - P1 - When ENTER is pressed with P1 on the display, the data stored in the memory of the instrument are unloaded (DUMP); press the PROG key to move on to step P2. During data dumping the messa- ge P1 appears on the upper display of the instrument.
ENGLISH 75 KEY SIMBOLS LIT BESIDES THE NUMBERS FUNCTION DESCRIPTION When the key (MEMORY CLEAR sub-function) is pressed with P1 on the display, all the sto- red data are erased. The instrument will display the message P1. At the end the instrument automatically returns to normal operating mode.
ENGLISH 76 KEY SIMBOLS LIT BESIDES THE NUMBERS FUNCTION DESCRIPTION After defining the storage time, press ENTER to return to normal operation, or press the PROG key to move on to step P3. In the storage function the instru- ment is able to store more than 30,000 acquisitions.
ENGLISH 77 KEY SIMBOLS LIT BESIDES THE NUMBERS FUNCTION DESCRIPTION P3+ = set Baud Rate P4+ = set year - P3 - When ENTER is pressed with P3 on the display, the Baud Rate of the RS 232C serial transmission may be modified. The and keys are used to select the desired value.
ENGLISH 78 KEY SIMBOLS LIT BESIDES THE NUMBERS FUNCTION DESCRIPTION P5+ = set month P6+ = set day - P5 - When ENTER is pressed with P5 on the display, the month may be set or changed.. The and keys are used to select the desired month. Then press PROG to move on to step P6 (the ENTER key is not active).
ENGLISH 79 KEY SIMBOLS LIT BESIDES THE NUMBERS FUNCTION DESCRIPTION P7+ = set hours P8+ = set minutes - P7 - When ENTER is pressed with P7 on the display, the hour may be set or changed. The and keys are used to select the desired hour. Then press PROG to move on to step P8 (the ENTER key is not active).
ENGLISH 80 KEY SIMBOLS LIT BESIDES THE NUMBERS FUNCTION DESCRIPTION P9+ = enable/disable self cut-out - P9 - When ENTER is pressed with P9 on the display, the instrument enters the program which enables or disables the self cut-out func- tion when it is in storage mode and with a set storage interval higher than or equal to 1 minute.
ENGLISH 81 KEY SIMBOLS LIT BESIDES THE NUMBERS FUNCTION DESCRIPTION P10+ = select type of printing automatically. When the ON/OFF key is pressed, storage is interrupted and the instrument switches off. 0 1 With a set storage interval higher than 1 minute, the display does not switch off automatically; it remains always lit and goes on storing.
ENGLISH 82 KEY SIMBOLS LIT BESIDES THE NUMBERS FUNCTION DESCRIPTION DATA CALL P11+ - P11 - When ENTER is pressed with P11 on the display, the instrument enters the program for calibrating the instrument.
ENGLISH 83 KEY SIMBOLS LIT BESIDES THE NUMBERS FUNCTION DESCRIPTION Different blocks can thus be for- med, all ending (during unloading) with the report giving the maxi- mum, minimum and mean values. The Serial Out/Memory symbol remains lit for the whole storage period.
ENGLISH 84 KEY SIMBOLS LIT BESIDES THE NUMBERS FUNCTION DESCRIPTION ENTER with RCD During programming this key is used both to enter the desired program and to confirm the value of the parameter considered.
ENGLISH 85 KEY SIMBOLS LIT BESIDES THE NUMBERS FUNCTION DESCRIPTION sh at a frequency of 2 Hz when the RCD key is pressed, it means that the RCD function has stored more than 30,000 acquisitions and cannot continue any further. After having taken note of the max.

measuring unit. * Press the Unit A or B key to select the temperature measuring unit in °C or °F. 4. Switching off the instrument. * The instrument is switched off by pressing the ON/OFF key. * Because of the Auto Power Off function the instrument may switch itself off during measure- ments.
TEMPERATURE MEASUREMENT Immersion temperature measurements are performed by introducing the probe to a minimum depth of 60 mm into the liquid in which you want to take the measurement; the sensor is housed in the end of the probe. To take measurements in air , the probe must be pointed in a transverse direction to the air flow.
their low heat conductivity. 12. The probes are not insulated from their external casing. Be very careful not to come into contact with live parts (above 48V) as this could be dangerous not only for the instrument but also for the operator, who could suffer an electric shock.
LOW BATTERY WARNING AND BATTERY REPLACEMENT When the battery has run down and its voltage has reached the limit value of 7.2 Volts, the symbol appears permanently on the display and an alarm beep sounds at regular intervals of about 15 seconds. In these conditions the battery should be replaced as soon as possible.
FAULTY OPERATION WHEN SWITCHING ON AFTER CHANGING THE BATTERY Repeat the battery changing procedure, waiting for a few minutes to allow the circuit condenser capacities to be completely discharged, then insert the battery. WARNING ON USE OF THE BATTERIES * If the instrument is not to be used for a long time the battery must be removed.
The transmission parameters with which the instrument is supplied are: * Baud Rate 19200 Baud * Parity None * N. bit 8 * Stop bit 1 * Protocol Xon/Xoff The data transmission speed may be changed by pressing the PROG key on the instrument to alter the set-up parameter P3.
At the end of data dumping the instrument returns to normal display. It is possible to stop and resume data dumping by repeatedly pressing the ENTER key. Once data dumping has been stopped it may be terminated by pressing the PROG key. Memory clear Press the PROG key twice until P1 appears on the display.
