LB4071-101
Fa'amatalaga:
The IEC ‘MULTI – COUNTER’ is a compact and versatile instrument for general laboratory timing to 0.1 ms, counting, measuring frequency or rate and for performing Geiger counting.
Each of the 3x modes (Timing, Counting/Freq and Geiger) has a set of ‘Functions’ to select the type of function you want for the mode you selected. All selection is by LED and the indication reminds you always of the mode and function that is operating
O vaega fa'apitoa o:
- High speed timing to 100 microseconds resolution.
- Large six digit LED display.
- All press button operation with LED indication of functions.
- Automatic loading memory up to a depth of 20 values.
- Memory items can be selectively deleted to remove errors. Memory items can be scrolled, totaled or averaged.
- Sockets for extension speaker.
- Speaker and volume control for all counts and frequency.
- Out put sockets for 12V.AC. supply for photogate lamps.
- Accepts both high voltage GM paipa ma maualalo voltage Fa'ailoga Alefa. E maua uma mai le IEC pe a talosagaina.
- Start/Stop TIME sockets also operate as remote Start/Stop sockets when running in COUNT, FREQUENCY or GEIGER modes.
Umi: 375mm

Maualuluga: 107mm
Mamafa: 2.4kg
Fa'amatalaga:
POWER: 220/240V.AC 50/60Hz.
SA'O: O gaioiga uma e feso'ota'i ma taimi ma taimi e loka tioata fa'amautinoaina le sa'o lelei e sili atu nai lo: 0.01% +/-1 numera aupito itiiti.
O galuega uma e fa'atonuina e le microprocessor.
Malosiaga Muamua Ki:
O lo'o fa'apipi'i i totonu le IEC 3 pine fa'amau e talia ai le uaea fa'alava. Fa'apipi'i ile 240V.AC masani. alavai eletise. E tatau ona fa'amalamalamaina le fa'aaliga numera.
- Small LEDs indicate the Mode of operation and Function.
- Press MODE button to select the Mode of operation required.
- Press FUNCTION button to select Function required in that mode.
Fa'agaioiga Fa'amau:
- START: initiates timing, counting or Geiger counting.
- STOP: stops timing or counting and value is stored in memory.
- RESET: operates after STOP. Zero display and also performs an Auto Mode external connection check on START/STOP sockets.
- MEM UP/MEM DOWN scrolls and recalls active memory locations.
Manatua:
When STOP occurs by either press button or by remote socket, the last value is automatically stored into memory. When any value is stored, the small ‘MEM’ LED is on. When 20 values are stored (memory full), the memory LED flashes.
MEM UP/LALO
Buttons scroll through the active memory store. When the first or last stored memory is reached, a longer beep sounds.
AOFAIGA
Fa'amau fa'aopoopo mea taua uma e manatua fa'atasi. Oomi ma taofi se'ia o'o fa'alua fa'alogo. Ole aofa'iga ole tau ole manatua ole a fa'aalia a'o taofi le fa'amau.
AVRG
Button calculates the average of all the memory values. Press and hold until double beep is heard.
Average will display whilst button is held depressed.
FA'AMA'IA
Button removes selected memory values. Scroll to select the unwanted value. Press and hold button until double beep is heard. Selection is now erased from memory leaving the other values untouched.
Display shows ‘——‘.
MANINO
Button empties all memory values. Press and hold button until double beep is heard. Memory store will be empty and the small ‘MEM’ LED will be off.
Faiga:
Three different modes of operation are selectable:
- Taimi
- Counting & Frequency
- Geiger counting.
Taimi:
Va'aiga ta'avale:
0.0001s up to 99.9999 seconds, then Auto Ranges to 999.999 seconds by 0.001s.
Faiga taavale:
O lenei galuega e fa'atulaga e ala i le oomiina STOP ona RESET fa'asolosolo fa'amau. A seti, o le amataga ma le taofi o le taimi o le a tupu i luga o soʻo se suiga o le tulaga o fesoʻotaʻiga eletise START / STOP. E mafai e lenei mea fa'apitoa ona fa'asaoina le taimi ma le faigata ile potuaoga e ala i le fa'ate'aina o le mana'omia o le faia o feso'ota'iga fa'apitoa 'faia' po'o le 'gausia' mo su'ega.
E fa galuega eseese o le taimi:
AMATA / TAofi:
A suia le tulaga o feso'ota'iga START mo sina taimi e tamo'e le taimi. E leai se aoga o feso'ota'iga amata. A suia le tulaga o feso'ota'iga STOP mo sina taimi e tu le taimi ma utaina le manatua.
PHOTOGATE:
A suia le tulaga o feso'ota'iga AMATA e tamo'e le taimi. A toe fo'i ia sockets i le tulaga muamua e taofi le taimi ma teu le tau i le manatua. O sockets e maua ai foi le mana e manaʻomia e faʻatautaia ai le tele o taʻavale photogate.
VAITAIGA:
A suia le tulaga o feso'ota'iga AMATA e tamo'e le taimi. A toe fa'afo'i fa'atasi soketi i le tulaga muamua e leai se a'afiaga. A toe suia ia lava sockets, e teuina le tau i le manatua, toe setiina le taimi ona amata ai lea o le taimi i le isi vaitau. Ina ia taofi le taimi lolomi STOP.
PENDULUM:
When the status of the START connections is changed the timer runs. When same sockets revert to original status there is no effect. When same sockets are changed again, there is no effect. Upon the fourth change, the value is stored in memory, the timer is reset and then starts timing the next pendulum period. To stop timing press STOP. Effectively this is a double ‘PERIOD’.
Faitauina & Faatele:
O fa'amau AMATA ma STOP po'o le tu'ufa'atasia o sockets TIME START/STOP e fa'ataga ai le faitau ma le fuaina o taimi i le Amata pe Taofi. A taofi, o le tau mulimuli e teuina i le mafaufau.
Ulufale Tali:
Pulses o le 20mv P/P i le 100V e mafai ona faitauina. E mafai ona fetuutuuna'i le maaleale o le fa'aogaina o le faitau i le va o nei tapula'a. Mo fatuga maualalo, fa'aopoopo le SENSITIVITY seia o'o ina fa'ataunu'u le faitauga mautu ma fa'atuatuaina.
E fa galuega tauave eseese o le faitauina ma le fa'atele:
Fa'aauau:
Counting continues until Stop button pressed or Stop sockets change in state. Value is stored automatically.
100 SEC:
Faitau mo le 100 sekone. A uma le taimi lea, e taofi le faitau ma faʻaalia le aofaʻi. E otometi lava ona teuina le tau i le manatua.
10 SEC:
Faitau mo le 10 sekone. A uma le taimi lea, e taofi le faitau ma faʻaalia le aofaʻi. E otometi lava ona teuina le tau i le manatua.
FA'AFIO:
The pulses applied are counted per second and displayed as frequency to a maximum of 999,999Hz.
Starting and stopping of the frequency function is performed by the buttons or the sockets in the TIME mode section. Each time the frequency is updated, the last value is automatically stored in memory.
Faitauina Geiger:
O le seti o le GM VOLTS e tatau ona fetaui ma le ituaiga paipa o loʻo faʻaaogaina. O le lautele lautele o le Alpha, Beta & Gamma halogen ua tineia GM tube (ituaiga MX168 pe tutusa), le voltage tatau ona tusa ma le 450V.DC. mo le sili ona fa'atuatuaina ma le maaleale.
E fa galuega eseese a Geiger faitau:
Fa'aauau:
Fa'aauau le faitau se'ia oomi le faamau STOP pe suia le tulaga o socket STOP. O numera Geiger ta'itasi e fa'atatau i le socket e faitaulia. O le voltage faʻaaogaina i le GM tube e mafai ona fetuunai mai le 200 i le 600 V.DC. mo le lagona sili ona lelei ma mo suʻega e aofia ai 'Plateau Voltage'.
In addition to the normal high voltage GM tube system, ua gaosia e le IEC se mea fa'apitoa fa'apitoa ALPHA fa'apitoa, fa'atasi ai ma totonu. amplifier, lea e mafai ona fa'aoga mo le maualalo o le tulaga ole su'esu'ega o le Alpha Particle.
AOFAIGA
Faitau i luga ole 10 po o le 100 lona lua: A uma le taimi lea, e taofi le faitau a Geiger ma faʻaalia le aofaʻi. E otometi lava ona teuina le tau i le manatua.
TULAFONO:
O pulus ua iloa e faitau ile sekone ma fa'aalia ile taimi ole fua ile maualuga ole 999,999Hz. O le amataina ma le taofi o le faʻagaioiga masani e faia i faʻamau poʻo faʻamau i le vaega ole TAIMI. O taimi uma e taofi ai le galuega, o le tau mulimuli e teuina i le mafaufau.
Fofoga Fetalai:
The instrument has an inbuilt speaker to monitor the ‘GM clicks’ together with sockets for an extension speaker (8 ohm impedance). A speaker volume control is provided.
Lamp Fa'atosina:
O sockets e maua ai le 12V.AC. i le 1 amp mo Photogate lamps ma isi..
Mamao:
Duplicates the RESET button function. Using a long cable, this socket can be joined to the common or ‘GRND’ socket by a switch or press button to create a remote RESET control.
Fa'aopoopo mea fa'apitoa:
- Photogates for experiments.
- Geiger Muller Tube with tube holder and lead.
- Solid state ALPHA particle detector with holder and lead.
- Extension speaker, 8 ohm impedance.
