5. INTRODUCTION
METEODIGIT IV is a new hand-held measuring instru-
ment of LAMBRECHT. The intelligent connector offers
decisive advantages when connecting sensors because
all parameters are stored in on the connector itself;
repeat programming is thus no longer necessary.
5.1 Functions
METEODIGIT IV has one electrically isolated measur-
ing input suitable for all LAMBRECHT sensors. For
operation purposes the device incorporates a large
LCD display and a keypad.
5.1.1 Sensor programming
The connector programs the measuring channels com-
pletely and automatically. Programming of the connec-
tor will be done during manufacture.
Accordingly programmed are:
- Measuring
ranges
-
Dimension (2-digit)
-
Correction of measured values
- Scaling
All sensor data stored in the connector can be pro-
tected by means of a graduated locking function
against undesired access.
5.1.2 Measuring operations
The measurement input can be connected with double
sensors, individually scaled sensors and sensors with
function channels. You can move forwards or back-
wards from one measuring channel to the next using
the keypad. The data are shown constantly on the dis-
play.
Measured values
The measured value for the selected measuring point is
shown continuously with autozero and, as and when
necessary, with measured value correction.
Measuring functions
With some sensors, to achieve optimal measured value
acquisition, certain special measuring functions are
required. For certain sensors temperature compensa-
tion and atmospheric pressure compensation are avail-
able.
Maximum and minimum values
For each measuring operation the maximum value and
minimum value are acquired and saved to memory.
These values can then be displayed, output, or deleted
from memory.
Measured value memory
Up to 99 measured values can be saved manually.
These data can be shown successively on the display.
Differential measurement
It is possible, by setting the measured value to zero, to
perform relative measuring operations with respect to a
reference value.

7. POWER SUPPLY
Power can be supplied to the measuring instrument
with 3 AA alkaline batteries (included in delivery).
7.1 Battery operating and supply volt-
age monitoring
At a current consumption of approx. 16 mA the operat-
ing time will be approx. 150 hours. The current operat-
ing voltage is displayed each time the device is
switched on; this gives you a basis for estimating the
remaining operating time. When the remaining battery
capacity drops to approx. 10 percent, the LOBAT arrow
will appear on the display. If the batteries are
completely discharged the device will switch off. To
replace old batteries first unscrew the battery compart-
ment cover

on the rear of the device.
7.2 Switching ON / OFF, reinitialization
To switch the device ON briefly press and release the
key
ON OFF
r

in the middle of the keypad; to switch
the device OFF press and hold down the key
ON OFF
r
.
After the device is switched off all saved values and
settings are retained intact.
If interference (e.g. electrostatic) or a malfunction (e.g.
battery failure) causes the device to behave abnor-
mally, the device can be reinitialized.
To activate
RESET
press and hold down the key
CLR
r
when switching on. This will restore all settings – except
the device designation – to the factory default status.
8. CONNECTING THE SENSORS
All LAMBRECHT sensors can the connected to input
socket
(M0) at the measuring instrument.
