SAFETY CAUTIONS:
● Make sure the power is at “OFF” status before connecting the wires to avoid electric shock and strictly follow the connection diagram
given out by the factory.
● Make sure the power OFF when cleaning the product.
● Working beyond the stated power supply (90-250V AC) is prohibited so as to avoid damage to the product or cause fire.
● Make sure the OUTPUT RELAY is used at the rated load and electrical life, if the contact of the output reply works against the electrical
life, it may melt or burned or even cause fire.
● Install power switches and circuit breaker for power safety.
STOCK AND MAINTAINENCE NOTICE:
● Try to avoid interfere headstream, input signals cable should not be too long, better to use twisted-pair shielded cable, shielded layer
connected with singals low end.
● Prevent from violent vibration, shock and incursion of heavy dust.
● Stock long terms at 0~50 ć, under 35~85ˁRH environment.
● When instrument power supply has noises, paticularly when inductive voltage caused by relay or contact devices switch ONand OFF
result in serious interference, must configure filter or rheostat or noises absorber.

6.OPERATION INSTRUCTIONS
a. 1 set stage operation instructions:
1. ENTER SET VALUE PROGRAM: press “RST” key once to inter into modifying set value program, highest digit is flashing (note:
when LOCK=KP-2 or LOCK=KP-3, set value program is locked and can’t enter).
2. SET/MODITY SET VALUE: press “ ” key to shift digit, press “ ” key to increase value.
3. ESCAPE SET VALUE PROGRAM:
set or modified value can be automatically saved in the instrument. To escape the menu, press
“RST” key or no operaiton after 10s can quit the menu and return to mesuring estate.

b. 2 stage counter operation instructions:
1. CONVERT DISPLAY OF CURRENT SET VALUE : “SET2” lamp ON: current display is high limit set value; “SET1” lamp ON:
current low limit set value, by pressing “ ” key to convert current display of high and low limit set value.
2. MODIFY HIGH LIMIT SET VALUE: first to convert high limit set value to current display value; next to modify value method same as 1 stage.
3. MODIFY LOW LIMIT SET VALUE: first to convert low limit set value to current display value, next to modify value method same as 1 stage.
4. Modified value can be automatically saved in the instrument. To escape the menu, press “RST” key or no operaiton after 10s can
quit the menu and return to measuring estate. (Note: when “LOCK parameter=”KP-1” or “KP-3”, the parameters are locked and
read only)
1. High limit output: measureing value ≥ high limit set value, relay OUT2 or transistor open collector TR.OUT2 output, OUT2 lamp
(or HI) lamp ON (1 stage has only high limit output).
2. Low limit output: measureing value ≤ low limit set value, relay OUT1 or transistor open collector TR.OUT1 output, OUT1 lamp
(or LO) lamp ON .
3. Relay contact output: AC 250V 3A resistance load.
4. Open collector output: 30V DC max.100mA max.
c. Comparator output:
1. Update means is time interval of displaying measuring value. Displaying value and comparator output refresh meantime, refresh
time can be set by parameter “UPDA” in operation menu, range: 0~9S. When UPDA=0, intrument refresh displaying value and
comparator output status immediately after system finishes samplimng .
1. Press “MODE” key for 3s to enter into operation parameters menu, higher line display parameters, lower line displays param
eters set value, press “MODE” key to move to next parameter. By pressing “ ” and “ ” key can modify parameters value,
modified value automatically saved in intrument. To escape menu, by pressing “RET” key or no operation in 10s. ( Note: when
LOCK=KP-1 and LOCK=KP-3, except LOCK, other parameters are locked and read only.)
2.Parameters value and operation method:
1. Press “MODE” key for 3s to enter into operation parameters menu, higher line display parameters, lower line displays param
eters set value, press “MODE” key to move to next parameter. By pressing “ ” and “ ” key can modify parameters value,
modified value automatically saved in intrument. To escape menu, by pressing “RET” key or no operation in 10s. ( Note: when
LOCK=KP-1 and LOCK=KP-3, except LOCK, other parameters are locked and read only.)
2.Parameters value and operation method: (refer to next page)
3. Example of tacho meter:
On the roller equipments, to use a rotary encoder to measure roller tacho, rotary encoder pulse=10 P/R, and request tacho
meter to display direct roller tacho, method refer to below:
a. Connect all necessary wires of tacho meter according to connection drawin on product, power ON.
b. Enter into operation parameters menu, set input measuring mode=A(tacho).
c. Set deviden modulus=10 (other parameters value set by user’s needs)
d. Update time:
e. Operation parameters menu for frequency and tacho meter:
f. Operation parameters menu for linespeed meter:
2. Update time can be set according to needs of system, e.g.: a system request to return to “0” immediately after stopping input signals,
user can set small update time to comply with system; another example of measuring non-average speed equipments, request displaying
value not to change quickly, in this case, to set bigger update time, system will automatically increase filter modulus.
3. Note: for low speed equipments, in particular when input signals frequency ≤1Hz, beter to set update time(UPDA)=0; if set quick
update, possibly cause update cycle<sampling cycle and displaying value bicker between measuring value and “0”.
