Rishabh Dual Frequency meters (ZQ 2 in 1)
Polycarbonate housing having UL 94 V-0
All Rishabh meters are housed in robust case with classical finish. The case is made of polycarbonate, which is flame retardant and non-drip and confirms to international regulations UL 94 V-0. Polycarbonate is a very tough and light weight engineering plastic material which has got the best mechanical properties very close to a metallic housing. It is 10% glass filled, glass fibers give it extra toughness.
Knife edge Pointer
Pointer edge is a knife edge and is made of aluminium sheet of 0.05mm thickness. This makes it very light weight but at the same time, it is rigid by a specially designed V-profile. The sheet used is a pre-coated aluminium sheet so that the adhesion of the paint is very good. The pointer is fitted on to the cross arm by a special flapping process so that it can never disengage even in extreme temperature or presence of vibration or shock.
Two different frequency ranges in one case
This is the most important feature of this meter. We can measure and read two different frequency ranges having different voltages or two different frequency ranges having same voltage in one meter and that is why it is called 2 in 1 meter. It is having two different movements and two different scales.
Terminal screws and clamps
Self lifting terminal screws are connected to the terminal clamps. Self lifted clamps gets lifted with the terminal screw while unscrewing, this simplifies clamping of the connectors or wire and save the time
Terminal protection with click-fitting back cover
All Rishabh meters are supplied with a self-clicking back cover which covers the terminals. This is very important feature especially for the voltmeter because these meters are usually connected on the front panel which can be opened and can be hazardous for the engineer while the maintenance of the panel is being done. The self-click avoids problems of loosing the screws and washers.
Easy replacement of glass and bezel
Easy replacement of glass and bezel is possible in Rishabh meters at customer end without any tool. The glass with zero knob and bezel are click fitted in the meter.
IP-52 Protection
Rishabh meters conform to protection standard of IP-52 (optional IP-54 and IP-65 can be provided) as per IEC-529 (DIN 40050). The window flap shut automatically when the instrument is installed in a switch-board or instrument cut-out. The O-ring incorporation in zero knob ensures protection from fine dust particles and water.
Built-in Transducers using Surface Mount Technology (SMT)
Bulit-in transducer forming a single unit with the meter used for Frequency measurements. Built-in transducer PCBs with SMD manufacturing technology ensures the quality and reliability of the product.
