PORTABLE AC AND DC MAGNETIC FIELD MEASUREMENT
The TES10C is a handheld Gauss Meter designed to measure the magnetic field. Its small size, light weight and convenient carry suit laboratory, production and field use, and it provides a judgment function of magnetic field polarity. Unlike DC-only models, the TES10C measures both AC and DC fields, with switchable mT and Gs units, peak value hold and a quick zero setting.
1. AC and DC measurement — measures both AC and DC magnetic fields with a DC/AC selection key
2. Polarity judgment — judges magnetic field polarity, and shows N/S polarity indication in AC mode
3. Peak value hold — holds the peak reading so a transient maximum is not lost
4. Switchable units — readings can be changed over between Gs and mT
5. Quick zero setting — establishes the zero point quickly before a measurement
6. Compact and light — small size and light weight for convenient carry
7. 4.5-digit display — 4-1/2" digital display gives a clear, easy-to-read value
The instrument is supplied with a measurement probe and a power adapter in a carrying case, and the battery compartment takes four AA cells for cordless operation.

1. Select AC or DC first — choose the field type with the DC/AC key before taking a reading
2. Quick zero setting — zero the instrument away from the magnetic source before measuring
3. AC range selection — AC ×1 gives 0.01 mT resolution over 0.00–200.00 mT; AC ×10 covers the wider 0.0–2000.0 mT range
4. Surface measurement — place the Hall probe chip side against the magnetic surface for a reading closer to the measured value
5. Peak readings — use peak value hold when the field is transient or varies during the scan
6. Unit conversion — 1 mT = 10 Gs; switch the unit keys when working in either system
| Magnetic field | TES10A | TES10B | TES10C |
| Field type | DC | DC | DC and AC |
| Display units | mT | mT and Gs | mT and Gs |
| Resolution | 0.1 mT, 1 mT | 0.01 mT, 0.1 mT | 0.01 mT, 0.1 mT |
| Accuracy | ±2% / ±5% | ±1% / ±2% | ±1% / ±2% |
The model differences above are based on the supplied product data. The TES10C is the model of the three that measures AC as well as DC fields; the separate AC ×1 and AC ×10 ranges give 0.01 mT and 0.1 mT resolution respectively.
