الفني بيكشف على الجهاز دلوقتي.

A natural Egyptian pronunciation is:

il-fanni biyikshif ʿal-gihāz dilwaʔti

A few helpful notes:

• الفني = il-fanni
• بيكشف = biyikshif
• على الجهاز is often pronounced together as ʿal-gihāz
• دلوقتي = dilwaʔti

Also:

• ج in Egyptian Arabic is usually pronounced like g in go
• ق in دلوقتي is pronounced as a glottal stop ʔ, not a hard q

Here, الفني means the technician.

The word فني originally means technical or technician, depending on context. In this sentence, it is clearly a noun: the technician.

You may also hear other Egyptian words for a technician or repair worker, such as الصنايعي, but الفني is very common and sounds a bit more neutral or formal.

Because both nouns are definite:

• الفني = the technician
• الجهاز = the device / the machine

Arabic uses الـ as the definite article, like the in English.

Sometimes English translations may say a technician if the context is not specific, but the Arabic form here is definitely the technician.

بيكشف is the Egyptian Arabic present-tense form of the verb يكشف.

In this sentence, it means something like:

• checks
• is checking
• inspects
• is inspecting

The exact English choice depends on context. Because the sentence includes دلوقتي (now / right now), the best translation is usually is checking or is inspecting.

In Egyptian Arabic, bi- is a very common marker for the present tense.

So:

• يكشف is the basic imperfect form
• بيكشف is the normal everyday present form in Egyptian speech

This present form can cover both:

• habitual meaning: he checks
• ongoing meaning: he is checking

Here, دلوقتي makes it clear that the action is happening right now, so the meaning is progressive: is checking.

This is important: يكشف على works as a unit.

It does not just mean reveal on or something literal like that. In Egyptian Arabic, يكشف على often means:

• to examine
• to inspect
• to check

So بيكشف على الجهاز means he is checking the device.

You can think of على here as part of the verb pattern you need with this meaning.

That is a very normal learner question. The short answer is: because Arabic verbs often use prepositions differently from English.

In English, we say:

• check the device

But in Egyptian Arabic, with this verb, people often say:

• يكشف على الجهاز

So the preposition على is not something you should translate word-for-word. It is just part of how this verb is commonly used in this meaning.

This is similar to how English says:

• listen to
• look at
• depend on

The preposition is required by the expression, even if it feels arbitrary to a learner.

In this context, it is better to keep على.

If you remove it, the meaning may sound unnatural or may shift away from inspect/check. The form يكشف على is the normal expression for examine/check here.

So for this sentence, بيكشف على الجهاز is the safe and natural choice.

الجهاز literally means the device, the machine, the apparatus, or sometimes the appliance, depending on context.

It is a broad word. It does not only mean computer.

So it could refer to many things, such as:

• a machine
• a medical device
• an appliance
• a piece of equipment
• a technical unit of some kind

Also, in Egyptian pronunciation, جهاز is said with g, so it sounds like gihāz.

دلوقتي means:

• now
• right now
• at the moment

It is a very common everyday Egyptian Arabic word.

It is not the formal Modern Standard Arabic word. In more formal Arabic, you would expect الآن for now. But in spoken Egyptian, دلوقتي is much more natural.

Because of دلوقتي, the sentence clearly means the action is happening at this moment: The technician is checking the device right now.

Because in Egyptian Arabic, starting with the subject is very common and natural.

So:

• الفني بيكشف على الجهاز دلوقتي = The technician is checking the device now

This subject-first pattern is extremely common in everyday speech.

A learner who knows more formal Arabic may expect verb-first order more often, but colloquial Egyptian regularly uses subject + present verb.

So this word order is not unusual at all.

It can mean either one.

In Egyptian Arabic, the bi- present form often covers both:

• habitual: he checks
• current/ongoing: he is checking

Context decides.

For example:

• الفني بيكشف على الجهاز كل يوم = The technician checks the device every day
• الفني بيكشف على الجهاز دلوقتي = The technician is checking the device right now

So in your sentence, دلوقتي is what pushes the meaning strongly toward is checking.
