TENMA 72-9390 Pen Style Multimeter

TENMA 72-9390 meter is a cool pen style multimeter. It feels right in the hand and incredibly simple to use, and accurate as professional multimeter.

The meter is 181mm long, and comes with a single (negative) test lead, 3V Li-MnO₂ button cell, and instruction leaflet.

TENMA 72-9390 is 3000 counts, true RMS, pen style multimeter with following core features:

Check continuity, AC/DC voltages (up to 300V), resistance (up to 30 MΩ), diode and capacitance (between 0.001nF to 3mF).
Sleep mode
Digital mode selection with audible feedback
Automatic ranging
Data hold, Max/Min mode selection
Sharp display backlight and test lead LED (for input terminal) to work in poorly lit areas
CATIII 300V safety rated

This meter keeps the digital display is in your hand and eyesight. This makes for easy reading of the display and one handed access to the function keys. The function key layout of this meter is simple and solid. Because of that you can easily familiarize with this meter within a short amount of time.

I test this meter reading with Sanwa PC20 multimeter and GW-Instek GDM8034 bench multimeter, and it gives exact readings as above professional multimeters.

As a summery this is a very impressive pen style multimeter. It is easy to use, lightweight (90.2g with battery) and higher quality than its rated price. I like to highly recommended TENMA 72-9390 (especially) for electronic troubleshooting works.

This multimeter is available at element14 (formerly Farnell) and I got it from element14 Singapore within 1½ days. Complete technical specifications of this multimeter are available in here.

CD2003 - yet another simple FM radio receiver

In the last few days, we are looking for some simple FM radio receiver to integrate into one of our ongoing projects. For that, we try several FM radio receiver ICs including TDA7000, CD2003/TA2003/TA8164, CXA1019, and KA22429. Out of all those chips we select CD2003 (or TA2003/TA8164) based receiver for our project because of its simplicity and outstanding performance. Except to CD2003, Sony CXA1019 also perform well but we drop it because of its higher component count. We design our receiver based on Toshiba TA2003 datasheet and later we try TA8164 and CD2003 with the same circuit. Either CD2003 or TA8164 can directly replace TA2003 IC, and as per our observations, TA8164 gives excellent results out of those 3 chips. A prototype version of CD2003 FM radio receiver The PCB design and schematic which we used in our prototype project are available to download at google drive (including pin-outs of crystal filters and inductors ). Except for CD2003 IC, this receiver consist...

Arduino superheterodyne receiver

In this project, we extend the shortwave superheterodyne receiver we developed a few years ago . Like the previous design, this receiver operates on the traditional superheterodyne principle. In this upgrade, we enhanced the local oscillator with Si5351 clock generator module and Arduino control circuit. Compared to the old design, this new receiver uses an improved version of an intermediate frequency amplifier with 3 I.F transformers. In this new design, we divide this receiver into several blocks, which include, mixer with a detector, a local oscillator, and an I.F amplifier. The I.F amplifier builds into one PCB. The filter stage, mixer, and detector stages place in another PCB. Prototype version of 455kHz I.F amplifier. In this prototype build, the Si5351 clock generator drives using an Arduino Uno board. With the given sketch, the user can tune and switch the shortwave meter bands using a rotary encoder. The supplied sketch support clock generation from 5205kHz (tuner f...

Experimental narrowband FM receiver for 2-meter band

This project is about MC3362 and ADF4351 based modularized, 2-meter narrow band FM receiver. In this design, the receiver splits into three modules as RF preamplifier, MC3362 tuner, and ADF4351 oscillator. The RF preamplifier builts around BF900 dual-gate MOSFET. The tuner stage builts using the popular MC3362 , low power narrowband FM receiver IC. For the oscillator, we use the ADF4351 DDS RF signal generator module. The core component of this receiver is MC3362 IC. This IC was designed by Motorola and is no longer in production, but this IC is still available to purchase in many online stores . The chip we used in this receiver was purchased from a local electronic component store for LKR 75 (USD 0.2). The RF preamplifier used in this receiver extracts from the N.Ganesan's (VU3GEK) LRR200, 2-meter band FM receiver project . Prototype version of the RF preamplifier. In this prototype, the above preamplifier was built as a module using a Manhattan construction technique. Th...
