PACE Tallis Transfer Standard Calibrator

The rear case of the DPI 104IS is not available as a spare part.
Special tooling is required to fit the pressure sensor into the case, we do not offer a repair service on the DPI 104IS.

With the scaling factor set to 1, the Voltage Output will be 0V to 5V corresponding to 0 to Full scale Pressure.
The accuracy of Voltage Output is 0.1% FS above 50mV, below 50mV no accuracy is specified.

The sensor to PCB cable is available as a spare part, the part number is IS104-2.

The instrument has detected an error at start up. First try resetting (restoring) the instrument by holding down all four buttons until the instrument goes off, the instrument will then restart.
If this does not cure the problem then check the transducer lead for bad connections or replace the lead if a spare one is available. If the transducer lead is OK then disconnect the battery for a few seconds and then re-connect it.
If the error is still present then the instrument will need to be returned/replaced.

You cannot switch over the mainboards as the mainboard contains all the calibration and temperature compensation data for the sensor, effectively the PCB and sensor are matched.

From the menu select the Tare function. Change the Tare function from “t off” to “t on” (leave the tA value set to zero), exit from the menu.

With the instrument displaying the pressure reading hold down the Enter key until “done” is displayed. The pressure reading
should now read zero.

The Quick Fit Adaptor is the same as the swivel connection on the PV62XG pressure bases, DPI 611 and DPI 612.

This allows the use of the IO620-HOSE’s and the IO620-BSP/NPT adaptors.

The remote gauge sensor is capable of measuring negative pressure but it is usually only calibrated in the Positive direction.
Negative Calibration is something we offer as an option on the DPI 705.
Below is what we state on the datasheet for Negative Calibration.
Please note there is no adjustment for the Negative direction, so accuracy is quoted as a percentage of the compound range. For a ±350 mbar sensor this would be a range of 700mbar.
Unless Negative Calibration is ordered at the time of manufacture there is no guarantee that the instrument will meet this specification as sometimes we need to select the sensor in order to meet the Negative specification.

For the DPI 705E it was recommended by our chief engineer to use the Autoclave 9/16 x 18 UNF connection on high pressure ranges (≥350 bar) due to the stress on the connection and to comply with the Pressure Equipment Directive (PED).
We do not supply adaptors for this connection as accessories with the DPI 705E, but we do supply an adaptor for the DPI 104 and PACE 1000 that have the same connection.
The adaptor used on the DPI 104 is a 9/16 x 18 UNF female to 3/8 BSP male, part number 182-190.
The adaptor used on the PACE 1000 is a 9/16 x 18 UNF female to 1/8 NPT female, part number IO-ADAPT-9/16AC.
If these are not suitable then alternatives are available from pressure fittings companies such as Swagelok, Parker, Staffordshire Hydraulics etc.

IMPORTANT NOTE: The PACE 1000 adapter IO-ADAPT-9/16AC has a pressure rating of 15000 psi / 1000 bar. Therefore the adapter is suitable for the DPI 705E internal ranges 350 bar/700 bar and external ranges 350 bar/700 bar/1000 bar but would it not be suitable for the external 1400 bar range.

The part numbers for the battery terminals with the pin pre-fitted are:
Positive Terminal IA2505-1-V0
Negative Terminal IA2505-2-V0

The display update rate is 2 Hz.

However for the DPI705 non IS version the same carry case is used for both instruments.

The carry case for the DPI 705E-IS is different to the carry case for the DPI 705-IS.

IO705B, carry case for the standard DPI 705 and IO705E-CASE, carry case for the standard DPI 705E both have the same internal part number.

The date stated on the calibration certificate is correct.

During manufacture the internal sensor of the DPI 705E is calibrated on a production calibration rig.
The sensors have an inhouse calibration period of 15 months and if unused will be recalibrated every 3 months.
This ensures that once fitted into a DPI 705E the calibration period will be at least 12 months when the instrument is shipped.
This is mentioned in section 3.1.4 of the user manual.
