Entretien Et Calibrage - Conrad VC-608 Bedienungsanleitung

b) REL
When measuring a reference value, the difference between the held and the present-
ly measured value is displayed to you. This special function is particularly helpful
when ascertaining the lower resistance without the measuring leads' resistance, or
with measured quantities that alter slowly.
The function is switched on by pressing "REL". As a result, the REL symbol appears
in the display's top line. When measuring the resistance, the DMM switches to the
highest range. The "OL" display disappears by pressing the REL push button and is
set to "00.000".
You can quit this function by pressing REL again.
Note!
The REL function is only active when numerical values are being displayed. For
example, the function cannot be called up during the continuity test.
c) LIGHT
The background lighting is switched on or off every time "LIGHT" is pressed. Due to
the relatively high power consumption, the illumination should only be switched on
for a short time and switched off again as quickly as possible, in order to save ener-
gy. The illumination will be automatically switched off after approximately 30
seconds if you do not press the push button again after switching on.
d) MENU
Press "MENU". As a result, the so-called sub-functions will appear in the upper dis-
play block.
Press the push button again and the sub-functions will disappear from the display
again. The following sub-functions can be called up after one another in the display
block: AUTO OFF (automatic switch-off) - RS 232C (switching on the interface) -
MAX (maximum value registration) - MIN (minimum value registration) -+
PEAK (positive peak value registration) - -PEAK (negative peak value registration) -
AVG (average value registration) - RECALL (redisplaying stored measured values)
–STORE (storing measured values) - GO/NG (a type of comparative measurement).
The respective sub-function that has been called up will flash. Selection is made by
using the arrow push buttons (< = back and > = forward). The display block will dis-
appear again if you press "MENU" once more and you return to the present display.

Entretien et calibrage

Afin de garantir l'exactitude du multimètre pendant longtemps, il est conseillé de le
calibrer une fois par an. Le calibrage peut être effectué à un tarif avantageux par not-
re service de calibrage dans le cadre du "SAV 2000".
La procédure de remplacement des fusibles est décrite dans les précautions d'em-
ploi. Le remplacement de la pile est décrit au point "Manipulation du multimètre A".
Pour le nettoyage de l'appareil ou de l'écran, utilisez un chiffon propre, sec, non
pelucheux et antistatique.
Pour le nettoyage, n'utilisez jamais de produits de nettoyage
contenant des liaisons carbone, d'essence, d'alcools ou autres
produits similaires, car ils attaquent la surface de l'appareil de
mesure. De plus, les vapeurs de ces produits sont nuisibles à la
santé et explosives. N'utilisez pas d'outils à arêtes tranchantes,
de tournevis ou de brosses métalliques, etc. pour nettoyer l'ap-
pareil.
