Summary
ZDS2 slot-type ammeter is a measuring gauge indicated by magnetoelectric pointe
can measure two kinds of electrical signals simultaneously. Presently, this gauge is widely
in multifunctional module of standardized locomotive cab. Based on the designed techn
application of gauge can be extended for various railroad locomotive, mine locomotive,
and light rail.
It is endowed with following advantages: small volume, convenient installation, a
reading, with night lighting, stable reading, and high reliability etc..

Malfunction & Maintenance
1\Malfunction & simple maintenance
| Malfunction | Possible cause | Solution |
| 1 Pointer deviate "Zero" point | Zeroing rod may deviate | Use screwdriver to adjust zeroing |
| 2 Pointer operate reversely | Input signal connect reversely | Check connection |
| 3 No lighting | Wrong connection of lighting | Check the connection of lighting |
| 4 Pointer not move or | Wrong input signal or over-strong input signal | Check input signal and its magnitude |
Please contact supplier, if the above malfunctions could not be settled. Don't open the gauge
yourself.
2\The gauge has to be readjusted after every three months, in order to ensure the accuracy.
3\Without the allowance of supplier, please don't open the gauge for adjusting, otherwise it
will cause error. Please do not repair the inner pointer, pin tube, and movement yourself.
