Fluke has introduced high-performance portable oscilloscopes with two or four independently insulated input channels, IP51 dust and drip waterproof rating, and CAT III 1000 V/CAT IV 600 V safety rating.
Users can choose from 500 MHz, 200 MHz, 100 MHz or 60 MHz bandwidth models. Especially designed for plant maintenance engineers, there is a choice of either a two- or four-channel scope for the harsh conditions of industrial electronics. A 5000 count digital multimeter (DMM) is included in the two-channel models.
The 190 Series II has up to four independent floating isolated inputs, up to 1000 V and a sampling rate of up to 5 GSps (depending on model and channels used). Frequency spectrum analysis using FFT and automatic capture and REPLAY of 100 screens, as well as a deep memory of 10 000 points per trace waveform capture (scope mode), are all features of this new-generation oscilloscope.
The instrument’s software features Connect-and-View triggering for intelligent, automatic triggering on fast, slow and even complex signals. ScopeRecord Roll mode gives 30 000 points per input channel for low-frequency signal analysis, and the TrendPlot paperless recorder mode with deep memory is provided for long-term automatic measurements.
The 190 Series II has an impressive seven hours of battery operation using BP291, as well as an ‘easy access’ battery door for quick battery swaps in the field. The isolated USB host port allows for direct data storage to a USB memory device. The scope is compact, weighing in at only 2,2 kg, and features a security slot to lock it down with a Kensington lock while unattended.
Also new to Fluke’s range for industrial testing are the ultra-rugged TL 175 TwistGuard test leads featuring a manually adjustable guard. The patented extendable tip shroud meets the highest electrical safety requirements to reduce tip exposure while providing the versatility needed for most measurements. Simply twisting the test lead cuts the exposed probe tip length from 19 mm to 4 mm. Extra-heavy duty strain relief on both probe-end and plug-end has tested beyond 30 000 bends without failure.
WearGuard double insulated silicone leads ensure added safety as each lead has two silicone insulation layers: red or black on the outside and white inside. Any white showing through warns of nicks or scuffs in the insulation. The double insulation also means they can withstand high temperatures and remain flexible in cold temperatures.
The leads are CAT II 1000 V (extended) or CAT III 1000 V and CAT IV 600 V safety rated (retracted). Universal input plugs are compatible with all instruments that accept standard 4 mm shrouded banana plugs.
