Gossen Metrawatt M227B - METRAHIT 27I Insulation Tester, Milliohmmeter, Multimeter, Data Logger

What’s Included

The METRA HIT 27I is used additionally for service and repair work performed on airplane and helicopter electrical systems (voltage, insulation, milliohm and temperature measurement). In addition to its own multimeter functions for electrical quantities, the instrument also includes a mega-ohm measuring function with insulation test voltages of 50, 100, 250 and 500 V, as well as temp

Easy Operation

Operation is very easy. Simply connect the low-resistance device under test to the instrument with the included measurement cables, Kelvin clips or 4-pole probes (KC27), and select the ideal measuring range.

Integrated Measured Value Memory and Interface

Each METRA HIT 27 is equipped with a measured value memory module and can thus be utilized as a data logger or a recording instrument for all measuring functions. Measurement results can be transmitted to a PC either off-line via the optical interface which is furnished as standard equipment, or online with an optional bidirectional adapter. In this way, for example, characteristic voltage and temperature curves (see figure below) can be displayed and analyzed in line recorder format relative to real-time, or individual measured values, e.g. voltages for each of the cells in a storage battery, can be saved with the DATA Hold function and analyzed at a PC in tabular form.

METRAwin 10/METRA HITMETRAwin 10/METRA HIT (software option): Recorded characteristic temperature curve and triggering characteristics (2-channel recording with 2 METRA HIT instruments) plus evaluation at a PC.

METRAwin 10/METRA HIT Software Option

Measurement data recorded to the measured value memory module can be evaluated at a PC if required with the help of the IR interface supplied as standard equipment and a bidirectional IR adapter (BD adapter) with conversion to the RS 232 protocol. METRAwin 10/METRA HIT software (see above figure) is recommended to this end, and is suitable for display, analysis and documentation of measurement results using Windows XP, VISTA or 7. The software is available as an accessory. User-friendly complete packages (e.g. the BD Pack or the complete METRA HIT 27AS case) are easy to connect and install and include everything required for high performance measurement data processing.

Offset Balancing

Automatic offset balancing is provided for the lower measuring ranges. Manual offset balancing, as required with the METRA HIT 17 predecessor model, is thus no longer necessary

Protection Against Operator Error

The METRA HIT 27 is safeguarded against erroneous short-term connection to devices under test with fault voltages of up to 600 V by means of protective devices.

Test Functions and Automatic Functions

All METRA HIT 27 instruments are equipped with diode and continuity test functions, as well as automatic and manual measuring range selection and battery shutdown.
