METRISO C

Insulation and Resistance Measuring Instrument

Special features for insulation resistance measurement

• Quick testing with limit value and signal lamp

• Auto-ranging for insulation resistance measurement over the

entire scale range for quick determination of the measured

insulation value

Special features for resistance measurement (low-resistance)

• Quick testing with limit value and signal lamp

• Automatic polarity reversal for recognition

of interference voltage

Special instrument features

• Hold function: the measured value is frozen at the display

after the measurement key is released.

• Measured values can be stored to memory with reference

to electrical circuits, distribution cabinets and other objects

thanks to alphanumeric entry.

• Data interface for transmission of measured values, and

for software updates

• Convenient report generating software,

can be expanded to a comprehensive database

Display

The LCD window consists of a backlit dot matrix which is used

to display menus, configuration options and measurement

results, as well as online help. Various user interface languages

can be selected, depending upon the country in which the test

instrument is used.

Operation

The instrument is very easy to operate. A multifunction key allows

for one-handed operation when selecting menus and starting

measurements. Basic functions and sub-functions are selected

with the help of four softkeys.

Battery Charge Level Indicator and Device Self-Test

A battery symbol in the main menu with 5 segments ranging from

depleted to fully charged keeps the user continuously informed

concerning battery charge level.

The test instrument is switched off automatically if the batteries

are depleted, and it includes a charge control circuit for safe

charging of rechargeable NiMH or NiCd batteries.

Test patterns can be queried one after the other in the self-test

mode, and display LEDs and relays can be tested.

Sturdy Housing for Rugged Use

Soft plastic jacketing protects the instrument against impacts, or

if it is inadvertently dropped.

Signal Lamps

The device recognizes errors in the electrical system automati-

cally, which are indicated with four lamps, (see following table).

Data Interface

Measurement data can be read out to a printer or a PC via the

integrated IRDA interface, providing the user with 3 advantages.

• Transmission of stored data to a PC for processing and

archiving, or for the generation of official reports

• Immediate print-out of all measurement data (via adapter)

Software Updates

The test instrument will never become obsolete thanks to

software updates which can be installed via the IRDA interface.

Updates can be performed by our service department as part of

our re-calibration service, or by the user himself.
