1) Safety Features and Precautions
You have selected an instrument which provides you with a high level of
safety.
The RI 10 Analog-Digital Insulation Tester is manufactured in
compliance with safety regulations IEC 61010-1/EN 61010-1/VDE 0413
part 1. When used for its intended purpose. safety of the operator, as well
as that of the instrument, is assured. In case of incorrect use or careless
handling, the safety of both user and instrument is not assured.
To maintain the safe and proper condition of the instr ment and to ensure
its safe operation, it is absolutely necessary to carefully and completely
read these operating instructions before using the instrument. These
instructions must be followed in all respects.
Observe the following safety precautions :
*
The instrument
must be operated
only by persons who
understand the danger of shock hazards and know how to
apply safety precautions.
Shock hazards
exist anywhere,
where voltages of more than 30 V may occur.
*
Do not work alone in shock hazardous environment while carrying
out measurement.
*
The maximum allowable voltage between any terminal sockets
and earth is equal to 600 V for voltage and 1000V for Insulation
resistance measurement.
*
Verify that the test leads are in good condition, e.g. no cracked
insulation, no open circuits in the leads or connectors.
*
Measurements under moist ambient conditions are not permitted.
*
Do not exceed the permissible overload limits of the measuring
ranges. Limit values can be found in the table in “12. Specification”.

Repair, Parts Replacement and Calibration
After opening the instrument, live parts may be exposed.Therefore, the
instrument must be disconnected from the measuring circuit prior to
opening its case for repair, replacement of parts or calibration. If repair or
calibration cannot be avoided, unless the instrument is open and live, the
work must be performed by a qualified person, who understands the
danger involved.
Faults and Extraordinary Stress
When it is realized that the safe operation is no longer possible, take the
instrument out of service and secure it against accidental use.
Safe operation is no longer possible -
n
When the instrument shows obvious sign of damage,
n
When the instrument no longer functions correctly,
n
After a prolonged storage under adverse conditions,
n
Due to severe stress due to transportation.
2 Initial Start-Up
Battery
Fit the instrument with the six 1.5V cells (IEC LR6 type) provided along
with the instrument.
Before you use the instrument for the first time or after storage refer
to section '' 3. Maintenance Battery ''
Switching the Instrument ON
Instrument can be switched ON :
1.
By pressing the ON/OFF button.
2.
By changing the function selector switch from current position
to desired function.
Switch-on is acknowledged by a sound signal.The instrument is now
ready for operation.
Attention !
Before opening disconnect the instrument from the
measuring circuit and ensure high voltage is not available
on leads.
Automatic turn-off
Your instrument turn off automatically, if any of the keys or the function
selector switch have not been activated for about 10 minutes in
insulation resistance range and 5 minutes in other ranges.
How to prevent automatic TURN-OFF
In order to prevent automatic “TURN-OFF” select “CONTINUOUSLY
ON” mode For this push TEST push button and the “ON-OFF”
pushbutton together when switching ON the instrument.
The symbol
is displayed on the LCD to indicate this
“CONTINUOUSLY ON” mode.
Switching the Instrument Off
Press “ON/OFF” pushbutton for a longer time.
3.
Selecting Measuring Functions
The desired measuring function is selected with the Function selector
switch.
4.
Liquid Crystal Display
4.1
Digital Display
The digital display shows the measurement value and decimal point.The
selected measuring unit and function are displayed.
4.2
Analog Display
The analog indication gives the dynamic performance of a moving coil
mechanism.This is especially advantageous for the observation of
measurement value fluctuations and for calibration procedures.
