补偿死区损失的两种最常见的技术是生存时间延长和无损计数。后者给出了更好的结果比前者的情况下，计数率的变化显着的测量过程中，但计算的不确定性与光谱计数是不明确的。为了克服这一缺陷，ORTEC DSPEC Plus采用改进的零死时间（ZDT）方法进行无损计数，并计算ZDT谱的方差。在DSPEC中动态计算ZDT校正，以产生校正数据谱和逐通道不确定度谱。
The two most common techniques to compensate for dead-time losses are live-time extension and loss-free counting. The latter gives better results than the former in cases where the counting rate changes significantly during the measurement, but calculation of the uncertainty associated with the spectral counts is not clear cut. To overcome this deficiency, the ORTEC DSPEC Plus was developed with an improved zero dead time (ZDT) method for loss-free counting and with the calculation of the variance of the ZDT spectrum. The ZDT correction is dynamically calculated in the DSPEC to produce both the corrected data spectrum and the channel-by-channel uncertainty spectrum.
