DESCRIPTION

Meter test device TL-1 has suitable ABS enclosure and a leathercase, which make easy handling of device and its accessories.

TL-1 is energized from internal battery or power network, fromwhich tested meter is supplied.In upper part of enclosure there is a socket with pin probes (orcables) and Neutral cable, ended with clamp for connection tometers terminal strip.The socket for measuring head (for automatic uncertaintymeasurements of induction and electronic meters) is placed inbottom part of enclosure. The head with a stand is an optionalaccessory of device TL-1.The device TL-1 is equipped with keyboard and LCD display forshowing measurements results and messages.In TL-1 memory are saved 12 mostly occurred meters factors,but user can insert any other factor.

Before start of meter checking, user should disconnect meterscurrent coil from consumer electric circuit.Current flow through meters current coil is forced by internalTL-1 circuit. This solution made possible elimination of additionaldevice for meters load (e.g. so-called dryer).TL-1 device enables meter testing with power about 1000 W,and measurement of meters starting current using step load(with step 5 W) in range 565 W, what is 0.5% of rated currentfor many meters.

Advantages: no external power source, which emits a lot of heat,

quick connection to meter (disconnected only meters load), display of percentage error of checked meter, power supply from measuring circuit, leather case for device with accessories.

PURPOSE

Microprocessor controlled device TL-1 is assigned for quick on-site meter testing. Percentage error of meter and its

starting current are checked. Easy maintenance and simple connection make possible checking of almost every induction

and electronic meter, in one- or three-phase circuit. On site test requires only disconnection of the meters current coil

from after-meter consumers circuit.

PURPOSE

Switch contacts anticoincidence meter MND-26 is designated for simultaneous measurement of open and close times upto 6 switch contacts, what enables determination of their operation anticoincidence.This meter allows analogue signals recording (e.g. currents in switching on and off coils and arming current).

DESCRIPTION

Meter MND-26 is microprocessor-based mobile device forswitch contacts anticoincidence determination in cycles:W, Z, WZ, ZW, WZW, with taking into account arming timetoo. Measurement can be started internally it performsautomatically in predetermined time, or it can be initiatedby external voltage signal 110 220 V AC/DC. It is possibleto start measurement by changing state of one contact (onlyanticoincidence measurement, but without necessity of voltagecontrol of switch).The results are stored in memory and displayed on LCD screen.It is possible to print results on internal printer (Kafka type) andsend them to computer or pendrive, using USB interface.

Duration of contacts vibration can be read from printed copy orfrom recorded time diagram, using computer software. Duringtime and current measurements, voltage of switch coils supplyis measured too.Meter with printer is placed in suitcase and can be suppliedfrom internal battery. Charging device is built in meter, printeris optional accessory.
