The testo 770-1 model is the standard version of the testo 770 series. This current clamp is ideal for daily measurement tasks including measurement of starting current and non-contact current measurement in cabinets. One of the two gripping claws can be fully retracted into the instrument, making it easy to grip cables in tight cabinets. The automatic recognition of measurement parameters ensures a reliable measurement function. In the current and voltage range, the instrument can detect direct and alternating current. It can also automatically select other parameters such as resistance, continuity, diodes and capacitance. The values are clearly shown on the 2-line display.

Advantages of the testo 770-1

• Fully retractable claw for maximum flexibility
• Auto AC-DC
• automatically selects parameters such as resistance, continuity, diodes and capacitance
• Clear 2-line display
• True effective value – TRMS
• Measurement of starting current

This clamp-on ammeter is ideal for non-contact current measurement in cabinets and confined spaces. One of the two claws can be fully retracted into the instrument and the unique gripping mechanism makes it easy to grip cables in hard-to-reach cabinets. The automatic recognition of measurement parameters ensures a reliable measuring function: in the current and voltage range, the instrument can detect direct and alternating current. It can also automatically select other parameters such as resistance, continuity, diodes and capacitance. The values are clearly shown on the 2-line display.

In addition to the features of the previous model in the same series, including non-contact measurement for confined spaces, the testo 770-2 also has a µA range and comes with a temperature adapter for type K thermocouples.

Advantages of the testo 770-2

• Fully retractable claw for maximum flexibility
• Auto AC-DC and clear 2-line display
• Electric motor starting current measurement function and μA measurement
• Temperature adapter can be connected for type K thermocouples.

The testo 770-3 current clamp is ideal for demanding measurement tasks in confined spaces. The movable gripping claw can be fully retracted into the instrument, making it possible to grip tightly bundled cables.

Thanks to improved resolution, highly accurate results are obtained even in the lower current range. The new testo 770-3 also has an extended voltage measurement range of up to 1000 V.

In addition, more specialized applications can be handled with the current clamp, such as starting current, power and μA measurements. An optional thermocouple sensor adapter is available, which can be used to measure both electrical parameters and temperatures (compatible type K sensor ordered separately).

The clamp ammeter automatically detects and selects AC/DC and other parameters, such as resistance, continuity, diode and capacitance. This makes handling easier and more reliable than ever before.

The measured values can be clearly shown on the display of the current clamp and in the testo Smart app. testo 770-3 can be quickly and easily connected to the testo Smart app and other Testo instruments via Bluetooth. In the app, you can display the measurement curve as a graph on your smartphone/tablet and save and send the measurement values directly in a report.

Advantages of the testo 770-3

• Increased accuracy in the lower current range thanks to improved resolution
• TRMS measurement
• Automatic AC/DC for voltage and large two-line display
• Bluetooth connection to testo Smart app and other Testo instruments
• Easy to use thanks to the retractable claw

The testo 755-1 ammeter/voltage tester detects and selects the correct electrical measurement parameter automatically. The testo 755-1 is the first voltage tester that can also measure current. You can check whether or not electrical circuits are de-energized, measure current or power consumption, and perform continuity testing with a single instrument. You can just start measuring – without making any switches or settings. The measuring tips can be changed quickly and easily and are very user-friendly. This means you don’t have to replace the whole instrument if damage occurs. Measuring point lighting also helps when lighting is poor.

The testo 755-1 is a true all-round instrument that makes daily work easier.

Advantages of the testo 755-1

• Easy to use thanks to automatic detection of measurement parameters
• Maximum voltage: 600 V
• Complies with DIN EN 61243-3:2014 and DIN EN 61010-1:2011
• Replaceable measuring tips
• Protective collar
• Ergonomic handle
• Suitable for almost all electrical measurements

Like the testo 755-1, the testo 755-2 can measure both current and voltage. The difference is that this instrument has a wider voltage range up to 1,000 V and can measure rotating magnetic fields. In addition, it has single-pole phase testing. The testo 755-2 ammeter/voltage tester detects and selects the correct electrical measurement parameter automatically. You can just start measuring – without making any switches or settings.

The measuring tips can be changed quickly and easily and are very user-friendly. This means you don’t have to replace the whole instrument if damage occurs. Measuring point lighting also helps when lighting is poor.

Compared to the testo 755-1, the testo 755-2 ammeter/voltage tester has a higher voltage range up to 1,000 V and can be used for measuring rotating magnetic fields. It also has a single-pole phase test for quick checks on whether conductors are live or not.

Advantages of the testo 755-2
