Notes on Safety, Usage, Maintenance and ServiceChapter 1
1.1 Safety notes
Please note the instructions and warnings contained in these operating instructions.
This instrument is built and tested according to EN61010-1 (protective measures for electronic
measuring instruments) .
Important! This instrument may only be powered with the power supply originally
delivered from the factory.
The instrument is in perfect working order upon leaving the factory. To maintain this condition and
to ensure safe operation, the user must check the instrument and the power cord regularly for
damage. A damaged power cord must be replaced immediately.
The instrument complies with the IP20 protection class according to EN60529.
Discharging via connectors may damage the instrument. Protect the instrument from electrostatic
discharge when handling and operating it.
Make sure that no external voltages greater than 70 Veff are applied to the measuring receiver’s RF
input since they may destroy the input circuits.
Do not cover the ventilation slots on the instrument. Doing so can lead to reduced air circulation in
the instrument, causing heat to accumulate. The electronic components can overheat as a result.
Important! Depending on the operating mode and the ambient temperature, overheating
can occur when the instrument is operated for extended periods in its
protective case and is on a flat surface. In this case, the instrument outputs a
warning message and then switches off.
Lithium-Ion accumulators must not be exposed to high temperatures or fire. If battery is replaced
incorrectly, there is a risk of explosion. Replace the batteries only with the original type (available
from a salesman in your area, wholesaler, or the manufacturer of the instrument). Do not short-
circuit the batteries.
Passage from the battery regulations (BattV)
This device contains a battery which incorporates hazardous substances. It
must not be disposed of I domestic waste. At the end of its working life it
should be disposed of only through the ESC customer service department
or at a designated collection point.

1.2 Usage notes
The guarantee for a new instrument ends 24 months after delivery.
The guarantee is invalidated if the instrument is opened!
Sharp tools (such as screwdrivers) can damage the plastic pane in front of the TFT display and
thus ruin the TFT.
The contrast of the TFT deteriorates at ambient temperatures below 5°C.
The TFT display does not reach maximum brightness until several seconds after the instrument is
cold-started.
The instrument reaches full measurement accuracy after about 5 minutes of operation.
Wireless DECT telephones and GSM mobile phones can cause malfunctions and incorrect
measurements if they are operated in the immediate vicinity of the measuring receiver.
1.3 Maintenance
The instrument is maintenance-free.
1.4 Cleaning
Clean the case and the TFT display with a soft, lint-free dust cloth. Never use solvents such as
diluents for cellulose lacquers, acetone or similar, since they may damage plastic parts or the
coating on the front panel.
Remove dust from the ventilation slots regularly so that the air circulation provided by the
integrated ventilator is not obstructed.
1.5 Calibration
The instrument should be recalibrated at least every two years. The instrument is automatically
calibrated at the factory if returned for service.
1.6 Service
