TEST PRODUCTS INTERNATIONAL LTD Equipment We Repair — By Category
TEST PRODUCTS INTERNATIONAL LTD Product Lines We Repair
Our engineers are trained on the full TEST PRODUCTS INTERNATIONAL LTD product range. Below are the major product families we service.
Insulation Resistance Testers
Hand-held and benchtop insulation testing instruments for motors, cables, and control circuits. Common faults include LCD display failures, battery contact corrosion, and sensor drift after moisture exposure in humid Indian industrial environments.
Earth Ground Testers
Portable ground resistance measurement devices used for earthing system compliance testing and safety verification. Typical failures include probe connectivity issues, unstable readings due to soil corrosion, and internal reference cell degradation.
Multi-Function Electrical Analysers
Advanced fault diagnosis instruments combining insulation, continuity, and voltage measurement in single portable unit. Common repair needs include sensor calibration drift, data storage circuit failures, and USB interface board replacement.
Portable Earth Continuity Testers
Lightweight single-phase and three-phase earth continuity checkers for rapid on-site electrical safety audits. Frequent issues include probe wear, relay contacts stiction, and internal fuse replacements after supply fluctuations.
Calibration Services for TPI Equipment
TPI test instruments require periodic recalibration to maintain measurement accuracy. Synchronics offers full calibration certification against ISO 9001 and Indian Bureau of Indian Standards compliance for manufacturing audit requirements.

Common TEST PRODUCTS INTERNATIONAL LTD Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in TEST PRODUCTS INTERNATIONAL LTD equipment arriving at our workshop.
- ✓LCD display segments fading or complete blackout — Moisture ingress during humid monsoon storage combined with LCD connector pin corrosion is typical in Indian coastal and tropical facilities. Display polarizer degradation also occurs after prolonged sunlight exposure in field testing environments.
- ✓Erratic insulation resistance readings or open-circuit fault codes — TPI probe connectors accumulate dust and mineral deposits from prolonged field use in Indian industrial sites. Internal sensor circuits suffer continuity breaks from thermal cycling between air-conditioned offices and hot plant floors.
- ✓Battery compartment corrosion preventing power supply — Alkaline and lithium battery leakage in dusty Indian manufacturing environments creates white corrosion deposits. Poor sealing of battery contacts accelerates chemical degradation in high-humidity foundries, textile mills, and food processing plants.
- ✓No earth resistance measurement or unstable ground readings — Test Products International Ltd earth testers rely on precision reference cells that drift after prolonged exposure to high salinity environments near coastal Indian ports and chemical plants. Probe spike corrosion from saline soils reduces coupling efficiency.
- ✓USB data download failure or corrupted test result memory — Multi-function TPI analysers accumulate static discharge damage in low-humidity Indian control rooms. USB interface circuitry suffers component-level failures from supply transients common in Indian industrial power networks without adequate UPS protection.
- ✓Probe connectivity loss or intermittent electrical contact — Test Products International Ltd probe receptacles wear after thousands of connect-disconnect cycles typical in high-activity Indian electrical safety audit departments and maintenance teams. Vibration from transportation loosens internal contact pins.

How do I know if my TPI tester needs recalibration versus component repair?+
Test Products International Ltd instruments should be recalibrated annually if used daily in Indian industrial environments, or bi-annually for periodic audit use. Signs of calibration drift include unstable readings, erratic display values, or measurements inconsistent with known reference standards. Synchronics offers free bench diagnostics to identify whether your TPI equipment requires component repair, recalibration, or both.
How do I send my TEST PRODUCTS INTERNATIONAL LTD unit for repair?+
