8. Product description
• The measured values are displayed on the multimeter (referred to below as DMM) in an illuminated LC display.
The measuring value display of the DMM comprises 4000 counts (count = smallest display value). The display
ranges from 0 to 3999.
• The VC-337 is suitable for DC and AC measurements up to 40 A. Due to the small measuring opening on the cur-
rent clamp, measurement errors due to an imprecise position of the current conductor are effectively prevented.
• The multimeter switches off automatically after a period of inactivity. This protects the batteries and extends the
battery life. The automatic power-off feature can be disabled.
• The DMM can be used to take measurements up to CAT III. It is suitable for use in hobby workshops and profes-
sional applications.
• If the maximum voltage measuring range of 600 V is exceeded, a continuous warning tone is emitted.
• If the battery is under voltage (≤ 2.1 V ±0.1 V), three beeps will sound and the multimeter will be turned off. This
prevents incorrect measurements due to insufficient battery supply.
• Protective caps may be attached to the angled test lead plugs. Remove these before inserting the test leads into
the multimeter.

Rotary switch (3)
The measurement modes are selected using the rotary dial. Automatic
range selection (“AUTO”) is enabled in some measurement modes. This
sets the measurement range automatically.
To turn the multimeter off, move the control dial to the “OFF” position.
Always turn the multimeter off when it is not in use.
