testo 6651 - 1.2 Product description 13
1.2.3 Display and keypad
The display option allows the testo 6651 humidity transmitter to be operated
via the display and four keys.
The LCD display consists of two 7-segment lines for displaying readings and
units and of an information line (for status messages, for example).
The brightness and contrast of the display and the background lighting
(permanent or off) can be changed via the user menu or the P2A software.
1.2.4 Service interface
Behind the service flap is the parameterizing socket (mini-DIN) as an
interface to the P2A software or Testo handheld instrument
(testo 400/testo 650).
1.2.5 Relay board (option)
This has a floating switch capacity of 250 V AC/3 A. The switching limits and
hysteresis as well as the function as relay for the collective alarm can be set
via the display or the P2A software. Further features include:
Function of changeover contacts (NC/NO contacts) freely selectable
12 terminals for a total of 4 relays.
If no relays are available, settings for monitoring limit values
or alarms can still be controlled via the display.
Only have the transmitter wired and connected by authorized
personnel with the voltage disconnected.
1.2.6 Analog outputs
For analog outputs, the testo 6651 has either
2 current outputs of 4 to 20 mA (2-wire) / 0 to 20 mA (4-wire) / 4 to
20 mA (4-wire) or
2 voltage outputs of 0 to 1 V/0 to 5 V/0 to 10 V (4-wire).
In 2-wire operation, channel 1 is used for the supply. The two channels are
galvanically isolated in both 2- and 4-wire operation.
[e-mail] www.Testo-Direct.com

14 testo 6651 - 1.2 Product description
The relay option and the background lighting of the optional
display are only possible in 4-wire operation.
1.2.7 Parameters
The following parameters are calculated:
Relative humidity in % RH and (technical)
Relative humidity in % WMO* (calculation according to the WMO
standard)
Temperature °C and °F
Dewpoint in °Ctd and °Ftd
Absolute humidity in g/m³
*It is possible that condensation appears as of a displayed humidity
starting from 70 % and is shown on the display. This unit is used in
meteorology, for example. According to the WMO, the Magnus
coefficient is used for sub-cooled water in the calculation of relative
humidity.
Calculated humidity variables correspond to the medium of
air. With other gases/gas compositions, deviations may
occur, e.g. with the enthalpy
1.2.8 Scaling
There are three types of min./max. values:
1 The measuring range
The maximum sensor performance is in this range. Values outside of
the measuring range are displayed via messages, for example.
Measuring range, see table (below).
2 Standard scaling
The output signals are assigned to this measuring range as standard:
- during delivery if no entries are made in the order code
- after exchanging the unit, the measuring range recorded in the
instrument is applied as standard.
[e-mail] www.Testo-Direct.com

testo 6651 - 1.2 Product description 15
The transmitter even retains its scaling with the voltage
disconnected.
Measuring range, see table (below).
3 The maximum settings for the manual scaling
- the values are not expressly given in the table. The maximum limits
can be calculated as follows:
X = difference between MIN. and MAX. value of the standard scaling
(Max. value of standard) + (50 % of X)
(Min. value of standard) - (50 % of X)
- It is thus possible to scale beyond the measuring range, e.g. for the
adjustment of the scaling limits to standard values of a PLC.
However, the physical measurement range limits are the deciding
factor when defining alarms.

1.2.9 Alarm handling
For upper and lower alarm limits, individual alarms as well as collective
alarms can be specified. If the collective alarm function is activated, an alarm
is triggered as soon as the alarm limit of an alarm is exceeded, if this alarm is
assigned to the collective alarm.
The testo 6651 monitors limit values using relays. If a reading is outside the
limit values, a relay to be specified by the user is switched.
If the reading reverts to more than a specified hysteresis below or above the
limit value, the alarm is cancelled.
In addition, information about the occurrence of error/status messages can
be provided by means of a collective alarm relay (see chapter 1.5, page 76).
If multiple alarm messages are activated at the same time,
the last alarm is shown. If the alarm is cancelled again, the
previous messages are no longer shown.
Example
If the condensation of the probe begins, the "Condensation"
message appears on the display and the "Start" status
display. If the condensation is over, the status display
changes from "Start" to "End".
