Different languages
With parameter '
Sprache/language
' you can switch the display language to
german, english, french or dutch.
Individual name for sensors and digital inputs
For every sensor/digital input an individual name can be assigned. This
name may consist of up to 8 characters max. (e.g. 'meatroom'). This name
appears on the actual display and on a printout. So there is a warranty of clear
assignment of sensor and value.
Over-/Undertemperature resp. humidity alarm
Each sensor input has its individual alarm setpoint (
H-limit / L-limit probe x
).
If the actual value passes this limits and the time delay is run down (
delay
probe x
), an error message will be generated.
Alarm repetition
After a reset of an error message, the message will be recreated after the
time set by (
alarm repeat
). This function can also be switched off.
Digital (Report) Inputs (not type 404 S, 2404 S)
The 3 present digital inputs work active-low, that means that a message will
be generated if no mains voltage in present at the input (12VDC with type
424/12V). With the digital inputs parameter '
1(al) 2(al2) 3(door)
' this inputs
can be enabled or disabled. For each input you can assign an individual
designation, 4 characters are possible. The default (factory) set designations
are 'al1', 'al2' and 'door'.
Each input has its individual time delay (
probe XX delay
), 'XX' corresponds
to the given text. An error message will be displayed and stored with the given
designation. If the parameter (
DI alrm w. accu
) is set to 'on', error messages
from the inputs are disabled during accu operation.
Real time clock
The integrated x-tal controlled real time clock can be corrected by only 24
hours. The automatic summer/winter-shift can be disabled for export purposes.
Without mains voltage the real time clock is battery backuped for typ. 10
years.
Accu operation (not type 404 S, 2404 S, 424/12V)
Without mains voltage the MiniMEP records no data, but stores the error
message that mains was lost.
If your application needs temperature recording also without mains voltage,
the unit must be supplied by an accu. For this reason the models with option
'A' (e.g. MiniMEP 424 A) are prepared for connecting an external accu-unit
(order name.: 'AccuSet'). This accu-unit ensures continuous recording for 4
hours minimum. The accu will be charged and monitored by an internal
charge controller.
During accu operation without mains voltage the alarm relay remains de-
actived. Parameter (
accu alarm mess.
) is able to suppress the accu alarm
message during accu operation.
Note: The accu unit is optional and not required for data storage!
Printout of values
A printer with a serial interface can be connected to the RS-232-
Interface at the front. Because at this time such printers are
disappeared from the market, this function becomes uninteresting.
We recommend to use a PC/Laptop with the software "CV-
Scheduler" to printout or to backup data.

Functions
Error memory
The last 6 occured errors will be stored with error code, name, date and time
and can be read on the parameter page
(last error 1
-
last error 6
).
Clear identification
Every MiniMEP has its own, individual serial number. This number is located
both on type label and in memory. You can read the number by scrolling
through the parameter page.
Recording
The MiniMEP records sensor values with the selected storage interval
(parameter '
recording
') and stores them into its non-volatile memory. If a
value leaves the specified range, display shows
'> +600°C' (+1112°F) resp. '< -110°C' (-166°F). The types 502/504 show
">+25°C (+77°C) resp. <-35°C (-31°F)". This values are not recorded.
Displaying °C and °F
With parameter '
Unit'
the display can be configured to show all temperature
values as °C or °F. Displaying °F, all values are shown with a 0,2°F
resolution.
