Day and night are set separately — and setting them too far apart is the mistake that has the screen jumping every time you pass a bridge.
ATA Taximeter – Irish market firmware – Pulsar Europe – PRIMUS RS-01 & S-01 – 2026
The meter reads the light around it and applies a different brightness by day than by night. That means the setting you make depends on the light you are sitting in when you make it. Set it once on a bright afternoon and once after dark, and you will have both ends covered properly.
The meter has four buttons. On the RS-01 they run 1, 2, 3, 4 from left to right, Button 1 on the far left and Button 4 on the far right. On the S-01 they run top to bottom, Button 1 at the top and Button 4 at the bottom. On both models, Buttons 1 and 2 move back and forth through the menu, Button 3 is enter, and Button 4 is back.
Because the two are independent, you can end up with a very low night setting and a very high day setting. The meter will then swing hard between them every time the light changes — under the Port Tunnel, into a multi-storey, out from under a bridge on a bright day. Keep the two within sight of each other and the screen settles down.
| CONDITIONS | WHAT YOU ARE SETTING |
|---|---|
| Bright daylight | Your day level. Set it high enough to read through a windscreen in low winter sun, not so high it glares. |
| After dark | Your night level. Bright enough for the passenger to read the fare, dim enough that it is not reflecting in the windscreen at two in the morning. |
That is not a brightness problem. Run the display test first, and if segments are missing or the screen is uneven, ring Pulsar Europe on +353 87 283 5120 — we have installers nationwide.
