Metrix MTX 3297Ex Schnellstartanleitung

QUICK START GUIDE
MTX 3297Ex, ASYC IV
Multimeters with 60,000-pt digital
display
Before using the multimeter for the first time, read the
ATEX/IECEx Instructions Manual.
It is used to make electrical measurements in potentially explosive
zones in categories 0, 1, 2, 20, 21, 22, and MI, per Directive
2014/34/EU (ATEX).
For measurements on protected electric circuits:
- In conformity for all zones: instrument group II, explosion group IIC
(explosive gases, vapours, and mists), temperature category T4.
- In conformity for the following zones: instrument group II, explosion
group IIIC, dust, fibres, and conductive or nonconductive
projections.
- In conformity for use in mines. Instrument group I, explosion group
I, methane and coal dust.
For connections to intrinsically safe circuits, check these connections:
refer to the user manual.
During measurements on an intrinsically safe circuit, the electrical
parameters must comply with the following values:
≤ or ≤
U 65 V (RMS value) I 5 A.
If you use this instrument other than as specified, the protection it
provides may be impaired, endangering you. The safety of any
system in which this instrument might be incorporated is the
responsibility of the integrator of the system.

Duty cycle DC±, then
resistive power PW±.
Activate for Peak+ Peak- measurements:
- Peak+: displays the maximum instantaneous peak
value of the measurement.
- Peak-: displays the minimum instantaneous peak value
of the measurement.
st
- 1 press: recording of PEAK+, PEAK- (on the 2nd
display unit).
The PEAK+ value is displayed as default.
- Subsequent presses: look-up of stored values
(volatile).
Precautions for use:
For your safety, use only the leads (15 A, 1,000 V) supplied with
the instrument.
They are in conformity with standard EN 61010-031. Before each
use, make sure that they are in perfect condition.
When the instrument is connected to the measurement circuits,
never touch an unused terminal.
Use only suitable accessories, those supplied with the multimeter
or approved by the manufacturer.
If the measurement category of the accessory is different from
that of the instrument, the lowest category applies to the whole
assembly.
Fuse: 10 A, 10x38, 1,000 V, F, breaking capacity > 30 kA
Inserting the batteries:
Remove the safety tabs from the batteries to make the
instrument operational:
- Unscrew the 3 screws,
- Remove the membrane covering the battery,
- Remove the battery safety tabs,
- Replace the membrane covering the battery,
- Tighten the 3 screws and press on ON key.

In an Ex-classified hazardous area:
-do not open the instrument
-use only qualified batteries.

Activation/deactivation of the low-pass
≈ 300 Hz filter:
The low-pass filter (4 th order) makes it
possible to measure the RMS voltage
delivered by an MLI type speed controller
(for asynchronous motor).

Select VlowZ in AC to make measurements in electrical
installations. The input impedance < 1 MΩ serves to avoid
measuring "phantom" voltages due to couplings between the
lines.
Activation of the MAX, MIN, AVG
measurements:
- MAX and MIN report the highest and lowest values of the RMS
measurement.
- AVG displays the mean value of the signal since the key press.
Time-stamped value for the MIN and the MAX [temporary
display (4 s) on the main display unit, followed by return to
present value.
If the time (h:min:sec) exceeds (9:59:59), «----» is displayed:

display unit).
The max. value is displayed by default.

Activate: .
Read the measurement value indicated on
the display unit.
"OL" is displayed if the value to be measured
exceeds the range limits or if the capacitor is
short-circuited.
For high values, the measurement cycle
includes the display of "run" with a "chaser"
decimal point. This means that acquisition is
in progress; wait for the display of the digital
result.
"Run" is displayed immediately, if the
previous measurement was in a small range.
