HIOKI Equipment We Repair — By Category
HIOKI Product Lines We Repair
Our engineers are trained on the full HIOKI product range. Below are the major product families we service.
HIOKI Clamp Meters (CM-Series)
Portable true-RMS clamp meters for AC/DC current measurement without circuit interruption. Common issues include loose current transformer cores, degraded battery contacts, LCD segment failures, and zero-drift in measurement circuits after thermal stress or impact.
HIOKI Power Quality Analysers (PQ-Series)
Three-phase and single-phase power analysers for harmonics, THD, voltage sag/swell monitoring, and power factor analysis. Repair focuses on current transformer calibration drift, voltage input module failures, SD card memory faults, and real-time clock battery depletion.
HIOKI Insulation Testers (IR-Series)
High-voltage insulation resistance testers (500V-5000V) for cable testing, motor winding diagnostics, and transformer insulation checks. Faults include high-voltage generator circuit failures, voltage regulation drift, measurement linearity errors, and probe contact deterioration.
HIOKI Digital Multimeters (DM-Series)
Precision digital multimeters with true-RMS, frequency, and resistance measurement. Common failures are ADC converter failures, battery management circuit degradation, terminal spring corrosion, and automatic range circuit malfunction.
HIOKI Data Loggers (LR-Series & GL-Series)
Temperature, voltage, and multi-channel data loggers for environmental and electrical parameter recording. Issues include SD card slot wear, sensor input conditioning failures, real-time clock drift, and firmware corruption.
HIOKI AC/DC Probes (CA, TA, CT Series)
Flexible current probes and high-frequency AC/DC probes for oscilloscope and analyser integration. Failures stem from cable micro-breaks, internal ferrite core saturation, connector oxidation, and frequency response drift.

Common HIOKI Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in HIOKI equipment arriving at our workshop.
- ✓Clamp meter zero-drift and measurement offset — HIOKI clamp meters experience zero-drift after thermal cycling in Indian manufacturing plants or outdoor power installations. Internal reference voltage regulator degrades and magnetization of the transformer core increases baseline offset, causing readings 2-5% above true values.
- ✓Power analyser harmonics measurement unreliable or absent — HIOKI PQ-series power analysers develop poor harmonic accuracy when current transformer coupling capacitors degrade or the FFT algorithm memory gets corrupted. Common in high-humidity Indian industrial environments where condensation affects PCB surface resistance.
- ✓Insulation tester high-voltage generator fails to output or drifts — HIOKI IR-series testers lose HV output due to oscillator circuit failures or transformer primary winding shorts. Extended storage in monsoon-prone Indian warehouses causes PCB corrosion on the HV boost circuit, reducing output regulation stability.
- ✓Data logger SD card not detected or corrupted files — HIOKI LR and GL series loggers develop poor SD card contact due to repetitive insertion wear or oxidation in high-temperature plant environments. Firmware file system becomes corrupted if unit loses power during logging write cycles.
- ✓Digital multimeter LCD segments missing or display ghosting — HIOKI DM-series multimeters display LCD segment faults after mechanical shock or from LCD controller IC failure. Segment drivers degrade in high-humidity environments common to Indian textile mills and chemical plants, causing incomplete numeral rendering.
- ✓AC/DC probe frequency response degraded or no signal pass-through — HIOKI CA and TA series probes fail due to internal ferrite core saturation, connector pin corrosion, or cable micro-breakage near the connector strain relief. Salt-air exposure at coastal Indian power stations accelerates connector corrosion.

Frequently Asked Questions — HIOKI Repairs
Do you repair HIOKI measurement instruments across India?+
Yes. Synchronics Electronics repairs the complete HIOKI product range - clamp meters, power analysers, insulation testers, data loggers, and AC/DC probes. We offer PAN India pickup and delivery from major cities including Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Nagpur, and Bangalore. All repairs are completed in our Vadodara, Gujarat facility with factory-standard calibration.
Why should I choose Synchronics for HIOKI power analyser repairs instead of local service centres?+
HIOKI power analysers require precision frequency-domain calibration and harmonic verification that demand specialized test equipment. Synchronics maintains HIOKI-compatible calibration standards, has genuine component inventory for PQ3100 and PQ3200 series, and provides detailed repair reports with before/after THD and frequency accuracy data. We guarantee measurement accuracy within factory specifications post-repair.
How long does HIOKI clamp meter repair typically take?+
Standard clamp meter repairs (battery replacement, zero-offset recalibration, LCD repair) take 5-7 working days including calibration verification. Complex repairs involving transformer core replacement or measurement circuit redesign may take 10-12 days. We offer express turnaround (48-72 hours) for critical field instruments at a nominal premium. Urgent repairs for power utilities and manufacturing plants are prioritized.
Do you handle HIOKI insulation tester high-voltage circuit repairs safely?+
Yes. Our engineers are trained in high-voltage safety protocols and work on HIOKI IR-series testers (up to 5000V) under controlled conditions. We discharge all HV capacitors, use insulated tools, and verify isolation resistance and safety compliance before release. All HV repairs include safety certification and dielectric breakdown testing as per IEC standards.
What warranty do you provide on HIOKI instrument repairs?+
Synchronics provides a 12-month parts and labour warranty on all HIOKI repairs. If a repaired unit fails due to the same fault within 12 months, we repair it at no charge. Calibration certificates are valid for 12 months from repair date. Extended warranty options are available for mission-critical instruments in power utilities and manufacturing facilities.
How do I send my HIOKI unit for repair?+
Pack the unit securely and courier it to our Vadodara workshop. Include a note with the fault description and your contact details. We will log it into our system and WhatsApp you a job number within 24 hours of receipt. Doorstep pickup is available in Vadodara, Ahmedabad, Surat, Mumbai, and Pune.
What is the cost of repairing a HIOKI drive or PLC?+
Repair cost depends on the model and the fault. We offer a free diagnosis — once we identify the fault, we provide a fixed quotation before proceeding. Typical repairs cost 20–40% of the new unit price. We will never repair without your approval.
What warranty do you provide on HIOKI repairs?+
All repaired units carry a 6-month comprehensive warranty covering the same fault and related issues. If the fault recurs within the warranty period, we repair it free of cost.
Do you provide a no-fix, no-fee guarantee?+
Yes. If we cannot repair your HIOKI unit after diagnosis, you pay only the diagnosis fee (₹500–₹1,500 depending on the product). The unit is returned to you at no additional charge.
