Connection/measurement
"
Before connecting the voltage source to be measured,
check that the MX403B is working. This is done with a
calibrated reference source or by measuring the refer
ence voltage in advance with a calibrated voltmeter.
"
Connect the MX403B to the voltage source to be
measured.
- Only extend the measuring lead with measuring
leads approved for CAT II 1000 V or CAT III 600 V,
or better.
- The maximum permissible length of the measuring
lead is 30 m.
- The measuring lead must not run through outdoor
areas, either in full or in part.
"
To reduce interference signals:
- Keep the measuring leads as short as possible.
- Connect the MX403B housing to ground potential.
- Use pairs of shielded cables (ensure approval),
connect the shield to ground potential.
- Route unshielded measuring leads close together,
channel by channel; avoid large loop areas.
- Twist the unshielded measuring leads together.
- Physically separate leads for measuring sensitive,
small signals from measuring leads connected to
sources that are subject to interference or highly
dynamic.
- Do not route measuring leads next to potentially
interfering devices such as motors, inverters, etc.
