2.1 Intended use

The CPH62I0 hand-held pressure indicator can be used as a calibrator, and for any application where an accurate pressure measurement is required, within hazardous

areas.

The hand-held pressure indicator has been designed and built solely for the intended use described here, and may only be used accordingly.

The technical specications contained in these operating instructions must be

observed. Should the hand-held pressure indicator be improperly handled or operated

outside of its technical specications, it has to be taken out of service immediately and

inspected by an authorised WIKA service engineer.

Handle electronic precision measuring instruments with the required care (protect from

humidity, impacts, strong magnetic elds, static electricity and extreme temperatures, do not insert any objects into the instrument or its openings). Plugs and sockets must be

protected from contamination.

If the hand-held pressure indicator is transported from a cold into a warm environment, the formation of condensation may result in the instrument malfunctioning. Before putting it back into operation, wait for the instrument temperature and the room temperature to equalise.

The manufacturer shall not be liable for claims of any type based on operation contrary to the intended use.

4. Design and function

4.1 Short description / Description

The CPH62I0 hand-held pressure indicator can be used as a calibrator and for any application where an accurate pressure measurement is required, within hazardous areas. Pressure sensors with ranges up to 1,000 bar are available for the CPH62I0 handheld pressure indicator. This hand-held pressure indicator recognises the range of the connected pressure sensor automatically and guarantees high precision.

Both gauge and absolute pressure ranges can be measured, and by using the CPH62I0-S2 with two connected pressure sensors, it is also possible to measure dierential pressure. Via menu selection, pressures can be displayed in bar, mbar, psi, Pa, kPa, MPa, mmHg or inHg. An integrated data logger and various other functions (such as Min, Max, Hold, Tare,

Oset correction, Alarm, Power-o, 3 Sample rates, Sealevel etc.) ensure that the instrument can be used for many dierent applications.

The hand-held pressure indicator and the pressure sensor are connected using a discrete connecting cable. When changing the pressure sensor, always connect and disconnect at the pressure sensor end of the cable. To connect the pressure sensor, rotate the plug till it locates in the guide slot, allowing it

to plug in. Then tighten the safety collar (by screwing it lightly in a clockwise direction).

When connecting the cable to the pressure indicator, the connector might not locate properly in the socket. In this event you should try holding the plug by the cable strain relief, rather than by the connector housing. If the plug is correctly located, it will slide in smoothly. To disconnect the pressure sensor hold it by the plug to release the connector lock. Do not pull the cable to release it.

WARNING!

For gauge sensors, the pressure compensation vent hole is found at

the top of the sensor housing. This vent (with integral membrane seal)

must be kept clear without fail!

Activating/deactivating ´TARA´ clears the max- and min-memories.

Zero-Point Adjust: (for gauge pressure sensors only) If there is no pressure applied

to the pressure ports the device should display 0. If there is a perma-

nent oset (and the device is being used under steady conditions),

a permanent zero point adjustment can be carried out. To carry out the adjustment, press ´TARA´ for approx. 5 seconds. (Please note: A

zeropoint adjustment can only be made if the dierence between the

display value and the factory calibration value is less than 2 %! E.g.

for a measuring range of 0 ... 25 bar, => zeropoint adjustment up to

0.5 bar is possible). To revert to the factory calibration, press ´TARA´ for

approx. 15 seconds.

A zero-point adjustment can only be carried out if the dierence

between the value on display is less than 500 digits! If a zero-point adjustment has been made, this will be signalled by the

message “nuLL-Corr“ being displayed briey as the device is turned on.

Dierential pressure: Pressing ´SET/MENU´ shows the dierence between the

measured values of Channel 1 and Channel 2 (DIF=CH1-CH2) in the

lower display. Pressing it again will hide it (only with the 2-channel

version and when 2 pressure sensors are connected).

6. Commissioning, operation

6.3.1 (Unit) Choice of pressure units

Depending on the pressure range, the pressure value can be displayed in any one of the following units: mbar, bar, Pa, kPa, MPa, mmHg, inHg or psi.

6.3.2 (SL) Sea-level correction for absolute pressure sensors

If an absolute pressure sensor is connected to the instrument, then the device displays the true absolute pressure measured by the sensor. This does not necessarily equate to the values given by weather stations, which give the pressure at sea-level. Usually the

sensor is situated above sea-level and therefore, if the value at sea-level (zero) is to be

measured, the pressure loss resulting from the elevation above sea-level must be consid-

ered! To correct the displayed value activate the “Sea-Level-Function“ (SL). (Setting is only possible, if an abs. pressure sensor is connected to sensor connection 1.) Then enter the sensor‘s height above sea-level in metres (Alti). When activated, the

display shows the SL-arrow and the device displays the absolute pressure value relative to sea-level.

When two absolute pressure sensors are connected, the sea level function for both corresponds to the setting of pressure sensor 1.

6.3.3 (rAtE) Choice of measuring rates: “rAtE-Slo, -P.dEt, -FASt“

Three options of measuring rate are supported. Two of them work with high measuring frequencies of over 1000 measurements per second. Whichever one of these was

selected during conguration (see above), this will be displayed in the lower display:

“P.dEt“ or “FASt“.

6.3.3.1 rAtE-Slo = standard measuring

Measuring rate 4 Hz, averaging and lter functions are active.

Application: Measurement of slowly changing or static pressures, e.g. leak testing, atmospheric pressure, highest accuracy, high noise immunity (EMI and unstable

measuring signals), low power consumption.

6.3.3.2 rAtE-P.dEt: Peak detection

Measuring rate > 1000 Hz, the value is displayed unltered. Application with logger function: Measurement of pressure spikes or uctuating

pressures with a resolution of < 1 ms. The cyclic logger function records the arithmetic mean value, the highest and the lowest peak during the chosen time interval.

Higher power consumption, measuring is sensitive to noise (EMI,..).

23WIKA operating instructions, model CPH62I0

6. Commissioning, operation

6.3.3.3 rAtE-FASt: fast ltered measuring

Measuring rate > 1000 Hz, but the value is ltered slightly (higher noise immunity than P.dEt, small peaks will be ltered out), apart from that, identical behaviour to P.dEt.

6.3.4 Averaging function

The averaging function acts on the displayed values (LCD and serial interface). It

is completely independent of the averaging within the logger function, please don‘t confuse them! The averaging integrates the measured values during a chosen time interval and then calculates the average display value. It is independent of the selected measuring rate

(slow, fast, peak detect). Until sucient values to calculate an average value have been collected (dependant on selected averaging time), the upper display shows “----“, the lower display shows a

´countdown´. During an active low-power-logging procedure the average is always deactivated.

Operation of min/max-value memory in conjunction with the averaging function:

■

If averaging is activated and ‘slow’ measuring rate is selected (rAtE-Slo), the min-/

max-memory value relates to the average display value.

■

If averaging is activated and ‘fast’ measuring rate is selected (rAtE-FASt or P.dEt), the

min-/max-memory value relates to the internal measured values (pressure spikes can

be detected).

6.3.5 Zero correction sensor 1 (OFS.1) and sensor 2 (OFS.2)

A zero displacement can be carried out for the measured value:

displayed value = measured value - oset

Standard setting: ‘o‘ = 0.00, i.e. no zero oset will be carried out. Together with the scale correction (see below) this factor is mainly used to compensate for sensor devia-

tions. Input is in the display unit.

6.3.6 Span correction sensor 1 (SCL.1) and sensor 2 (SCL.2)

The scale of the measurement can be inuenced by this setting (factor is in %):

displayed value = (measured value - oset) * (1+Scal/100)

Standard setting: ‘o‘ = 0.000, i.e. value is not corrected. Together with the zero oset (see above) this factor is mainly used to compensate for sensor deviations.

6.3.7 (P.oFF) Power o function

If no key is pressed, and no serial communication occurs during the interval set in

conguration (P.o), the device will automatically switch itself o to save battery power. If P.oFF = oFF then the automatic power o is deactivated.

6.3.8 (Out) Output

The output can be used as a serial interface (RS-232 or USB) or as an analogue output (0 ... 1 V).

6.3.9 (dAC.) Analogue output – scaling with (dAC.0) and (dAC.1)

Analogue output cannot be used during logger recordings.

WARNING!

Only use the analogue output with a passive voltmeter.

With dAC.0 and dAC.1 the analogue output can be easily scaled. It should be ensured that the analogue output is not overloaded, otherwise the output

value could be incorrect and battery life can be reduced. Loads up to approx. 10 kΩ are

not critical. If the display exceeds the value set by dAC.1, then the device will apply 1 V to the output. If the display falls below the value set by dAC.0, then the device will apply

0 V to the output. In the event of an error (Err.1, Err.2, no sensor, etc.) the device will

apply slightly above 1 V to the output.

Plug wiring:

WARNING!

The 3rd contact must be left oating! Only stereo plugs are permitted!

6.3.10 (AL.) Alarm

There are three possible settings: Alarm o (AL.oFF), on (AL.on), on (AL.no.So).

The following conditions will prompt an alarm to be displayed, if the alarm function is

activated (on or no.So):

■

Value is below lower alarm limit (AL.Lo) or above upper alarm limit (AL.Hi).

■

Sensor error (Sens-Erro)

■

Low battery (bAt)

■

Fe 7: System error

When an alarm occurs, the alarm arrow ashes, and, during serial communication, the ‘PRIO’-ag is set within the transmitted message.

6.3.11 (CLOC) Real time clock

The real time clock is needed for time-stamping each data point recorded within the logger function. As a result, the clock settings should be checked regularly. If the battery has been replaced the appropriate menu ‘CLOC’ will be accessed automatically.

6.4 Operation of logger

The device supports two dierent logger functions:

"Func-STOR":

Each time the ´STORE/QUIT´ key is pressed a data point will be recorded.

"Func-CYCL": Measurements will automatically be recorded at a dened interval, set

within the logger menu ‘CYCL‘ until the logger is stopped or the logger memory becomes full. Logging is started by pressing the ´STORE/ QUIT´ key for 2 seconds.

The logger records up to 3 measurement values for each interval:

■

Current or mean value (depending on logger setting, see below), Min-Peak and Max-Peak. (Sensor 1, Sensor 2, dierence)

To evaluate the data, WIKA’s Data logger evaluation software GSoft (V 2.3 or higher) must be used. The software also allows easy conguration and operation of the logger.

If the logger is selected (Func-STOR or Func-CYCL) the hold function is deactivated; the

´STORE/QUIT´ key is then used solely for the operation of the logger functions.

Min- and Max-Peak are, respectively, the minimum and the maximum measured values

during the last measurement interval. Therefore both the instantaneous pressure values

and the measured uctuations can be better analysed.

6.4.1 “Func-Stor“: Storing discrete measurements

In this mode, each time the ´Store/Quit´ key is pressed a measurement and its time stamp will be recorded. The data recorded can be viewed either on the display (an

additional menu item “REAd-LoGG“ is displayed when scrolling through the conguration menu) or through the serial interface and a PC running the GSoft software.

Max. number of measurements: 99

The data recorded includes the following values:

■

Sensor 1: instantaneous value at that data point

■

Sensor 1: Min-Peak, Max-Peak since last data point

■

Sensor 2*: instantaneous value at that data point

■

Sensor 2*: Min-Peak, Max-Peak since last data point

After each recording “St. XX“ will be displayed for a short time. XX represents the number of the data point.

If the logger memory already contains data: When the ´STORE/QUIT´ key is pressed for 2 seconds, the option to clear the logger memory will be displayed:

Viewing Recorded Measurements

Within the “LoGG-Stor“ function the measurements can be viewed directly on the instrument display as well as through a computer (“Func-CYCL“ only allows for the data

to be viewed on computer). Press the ´SET/MENU´ key for 2 seconds: The rst menu displayed is now “rEAd-LoGG“ (read logger data). By then pressing the ´TARA´ key, the

last measurement recorded will be displayed; pressing the ´TARA´ key again scrolls

between the dierent values related to this data point. Pressing the ´MIN´ key or ´MAX´ key selects dierent data points.

6.4.2 “Func-CYCL“: Automatic datalogging with adjustable cycle-time

The Logger cycle-time is adjustable (see Conguration). For example, setting “CYCL“ =

60: A measurement is made every 60 seconds. When the slow measurement “rAtE-Slo“ is chosen, additionally a low power function is available: “Lo.Po“. If “Lo.Po“ is on, the device only will take a measurement at the point of time of the recording. In between the recordings the measuring is not active. This decreases the power consumption enormously and therefore is recommended for long time recordings where no mains adapter is available.

Max. number of measurements: CPH62I0-S1: 10,000 CPH62I0-S2: 4,000

(at max. 64 recording sequences) Cycle-time: 1 ... 3,600 seconds (=1 h), selectable from the conguration menu

A measurement contains:

■

Slow measuring rate (rAtE-SLo):

- Sensor 1: current value at that data point

- Sensor 1: Min-Peak, Max-Peak since last data point

- Sensor 2*: instantaneous value at that data point

- Sensor 2*: Min-Peak, Max-Peak since last data point

- Instantaneous dierence (Sensor 1 - Sensor 2)*: at that data point

- Min-Peak, Max-Peak of dierence (Sensor 1 - Sensor 2)*: Min-Peak, Max-Peak

since last data point

■

Fast measuring rate (rAtE-FASt, -P.dEt):

- Sensor 1: average since last data point

- Sensor 1: Min-Peak, Max-Peak since last data point

- Sensor 2*: average since last data point

- Sensor 2*: Min-Peak, Max-Peak since last data point

- Average dierence (Sensor 1 - Sensor 2)*: since last data point

- Min-Peak, Max-Peak of dierence (Sensor 1 - Sensor 2)*: Min-Peak, Max-Peak
