9. Others
a. Change in accuracy class
b. Special conditions such as temperature,
humidity, atmosphere, vibration, etc.
1. All models are equipped with a terminal cap if requested.
2. Both 500 and 600V DC and rectier series resistors are now built in.
3. ECF-12NB, RCF-12NB and UuCF-12NB types:
1) Ammeter type was changed to the electronic device type and a transducer is now built in.
2) Terminal cap was attached.
3) Consumption VA was reduced.
4. RoHS compliant product (however, the taut band of the DCF-6, 8, 10 and 12N type 50μA and 100μA meters are non-RoHS products.)
Electric transducer system provided with □CF-6, 8, 10 models (□: E, R, U, Uu) The converter was reduced in size to unify with the □RG-3 type (with terminal cover).
The insulation category is CAT III 600V For the AC voltmeter and AC ammeter ACF-□ type (operating principle: moving-iron type), even without installing the insulating rubber. (600V is the maximum circuit voltage value that can be used)
The insulation category is CAT III 300V for meters other than those indicated above when using only the meter body (without the insulating rubber). (300V is the maximum circuit voltage value that can be used)
The insulation category is raised to CAT III 600V if the insulating rubber is installed on the panel board.
Features
1. Meter has a bright scale face due to the wide cover lighting surface.
2. Accuracy of readability has increased due to the long scale length compared to the meter’s size.
3. A variety of sizes are available so you can choose a meter that best suits the size of your switchboard.
Features Cover eliminates static electricity.
Equipped with special anti-static resin.
Maintaining an anti-static finish is not necessary.
Static phenomena will not occur even in low humidity.
