1. General Information 1.1 Applications The DIGISTANT® model 4420-V001 universal calibrator is ideal for testing and calibrating temperature measurement and control devices as well as documenting the measurement results. Due to its versatile functions, this portable device can not only be used on-site but also as a stationary unit in the test shop or laboratory. The device can measure and simulate voltage, current, temperature and resistance. The pressure modules of the 7131 series can measure and display pressures of up to 200 bar in the correct order of magnitude. Simultaneous transmission...

How to correctly charge/discharge the Ni-MH accumulator n It is advisable to discharge the accumulator completely at regular intervals (from twice a week to once a month, depending on the degree of use) and then recharge it. This has a relaxing effect on the accumulator, making it more reliable and durable. Long storage periods result in different charging levels in a multi-cell block, due to the different rates of self-discharge. In the worst case, this could lead to a pole reversal of the weakest cell during discharge. If it is at all possible for the charging unit to reverse the polarity of...
