Metrel MI 3136 InstalTest COMBO XC – Standard Kit

The Metrel MI 3136 InstalTest COMBO XC Installation Tester combines essential electrical installation tests with a modern colour touchscreen and onboard result storage. Suitable for installation verification to AS/NZS 3000 and testing to AS/NZS 3017, it brings insulation resistance, continuity, RCD testing, loop impedance and phase rotation testing together in one portable instrument.

The 4.3-inch touchscreen makes selecting tests, viewing results and organising records easy. Preset and adjustable PASS/FAIL limits help assess measurements, while automatic test sequences reduce repetitive setup when testing multiple circuits or RCDs.

The instrument uses the same operating software as the other Metrel testers of this generation including simple formats for organising site structures. Thes structures can be configured on the tester at the time of testing or uploaded prior to site visit from a Windows PC.

The MI 3136 features Autotest sequences with built-in preconfigured PASS/FAIL thresholds in accordance with AS3000 standards. 

The socket testing function checks earth continuity, polarity and correct circuit connections. Used with the optional A1195 resistor box at the switchboard, it allows socket testing without a lengthy trailing earth lead. An optional A1532 XA EVSE adaptor extends the tester's capabilities to compatible electric vehicle charging stations.

A rechargeable lithium-ion battery, USB-C charging, Bluetooth and Wi-Fi connectivity support everyday testing and data management. Metrel ES Manager BASIC software is included, with additional reporting and cloud functions available through optional licences.

Note: This product is an installation tester. It is not a portable appliance tester and is not intended for routine appliance test and tag work.

Nominal Voltages: 50V, 100V & 250V DC

Nominal Voltage: 500V DC

Nominal Voltage: 1000V DC

Displays the applied insulation test voltage. This is separate from the general voltage measurement function.

Measures protective conductor and equipotential bonding resistance using a minimum 200mA test current into a 2Ω load. Automatic polarity reversal and test lead compensation support reliable low-resistance measurements.

Measuring Range

General Data

• Supported RCD types include AC, A, F, B and B+
• Nominal residual current settings from 6mA to 1000mA, depending on the selected protective device
• Sine-wave, pulsed and DC test currents
• Test current starting polarity: 0°, 180° or both
• Trip time, trip current and contact voltage measurements
• Automatic RCD test sequences
• Selectable AS/NZS 3017 test settings

Available test currents, multipliers and test durations depend on the selected RCD type and test configuration.

Trip-out Time

Trip-out Current

The Australian socket test function combines earth continuity, polarity and correct connection checks into a single push-button sequence, with clear PASS/FAIL results.

The optional A1195 resistor box connects at the switchboard to support testing at socket outlets without a trailing earth lead. The resistor box is not included in the standard set.

Without RCD Protection
