DR series Meg Ohm Meter
User Manual
Thanks a lot for selecting products!
Before operating this instrument, please carefully read this manual and fully
understand its contents. If have problems, please contact our sales or distribu-
tors whom you buy from. This manual is subject to change without prior notice.
Warning
Please do not turn on the power supply until all of the wiring is completed.
Otherwise electrical shock, fire or malfunction may result.
Do not wire when the power is on. Do not connect the unused terminals. Do not
turn on the power supply when cleaning this instrument. Do not disassemble,
repair or modify the instrument. This may cause electrical shock, fire or mal-
function
Use this instrument in the scope of its specifications. Otherwise fire or mal-
function may result.
The use life of the output relay is quite different according to it capacity and
conditions. If use out of its scope, fire or malfunction may result.
!
Caution
This instrument should be installed in a domestic environment. Otherwise
electrical shock, fire or malfunction may result. The operating temperature
environment should between 0 (32F) to 50 (122F).
To avoid using this instrument in environment full of dust or caustic gas.
To avoid using this instrument in environment of strong shock or concussion.
To avoid using this instrument in environment of overflow water or explosive oil.
The instrument has the recovable protection parts.It can prevent demages in
case of short circuit.
★
Application
Professional measurement for various resistance with rapid inspection,
good linearity & precise.Various output controls enable the instrument to apply
with auto inspection for qualified product,& to act as electronic rules for posi-
tion control.What¡¯s more,it can act as not only meg ohmmeter with inbuilt
excitation voltage(100-500V) for insulation material,but also conductivity ana-
lyzer by changing inner calculate mode. In addtion,RS485 communication will
realize remote control by connect with PC/PLC.

Parameters setting
1. Alarm setting: In the displaying estate, press and hold SET key for more
E: 18-30V AC/DC
than 3 seconds, enter alarm mode parameters setting menu. Press <
</RST key, LED flashes, press
key to confirm. Press SET key to read the following parameters one by one.
2. The instrument will return to the measuring estate without any operation
for 25 seconds.
Special functions
1. Megohmmeter: In the deisplaying estate,press 《 〈/RST>3s,RUN(OUT)
lamp ON to clear last value,display volt/ampere.and prepare for next
measurement.
When it's under measurement,RUN(OUT)lamp OFF,no volt/ampere val-
ues display,but keep the last value measured.If OPEN displays,it means
ampere<0.1uA or resistance>500MΩ
2. For regular measurement,the instrument can be setted to a certain range
to judge if the object is qualified automatically.External output is available.
