<p>I've gotten a few emails asking for help about the Uni-T UT390B laser distance meter because the operating manual is written in Chinese. I've created a list of the unit's error messages in case it's useful for anyone developing with this device.</p>
<pre class="c"><code>enum {
ERR_BATTERY_LOW = 101,
ERR_CALCULATION = 104,
ERR_HIGH_TEMP = 152,
ERR_LOW_TEMP = 153,
ERR_OUT_OF_RANGE = 154,
ERR_WEAK_SIGNAL = 155,
ERR_STRONG_SIGNAL = 156,
ERR_BACKGROUND_ILLUM = 157,
ERR_DEVICE_SHAKING = 160
};</code></pre>
