Reference Conditions; Specifications - Metrix MX2B Notice De Fonctionnement

Temperature: 23°C ± 2K
Humidity 45% RH ± 5%
:
Position: horizontal ± 2°
Ensure that the pointer is at zero before starting any measurements.
Zero adjustment: open the device. Mechanical zero adjustment is carried out by
turning the transparent cover on the back of the null meter.
Ensure that the switch is correctly positioned.
When an estimated measurement is unknown, place the switch at the highest calibre,
then gradually reduce it until the appropriate calibre is achieved: the reading should
preferably be in the upper 2/3 of the range.
3-1 DC VOLTAGE
Connect the leads to the multimeter (be careful of switch position, see below) and
•
connect to the circuit to be controlled.
When an estimated measurement is unknown, place the switch at the highest
•
calibre, then gradually reduce it until the appropriate calibre is achieved.
To obtain voltage in V, multiply the appropriate range value by the reading
•
coefficient indicated in the table.
