Analyzer Q1
Witschi Electronic Ltd
To measure the voltage with a high load demand (
High Drain
), briefly press the start button; this
will switch on the load for 1 s. This load simulates the lighting or alarm function.
The
High Drain
measurement should not be repeated several times since the high load demand
quickly drains the battery.
10.3
Result Display
The voltage without load is displayed in analogue form in addition to the numerical results.
The
High Drain
voltage is only displayed when this measurement has been initialized by pressing the
start button.
Additional information about battery test is available in chapter 16.7.

GRAPH OF THE MOTOR PULSE
11.1
General Introduction
The Analyzer Q1 can record the motor current pulse as an oscillogram. In addition to the pulse
parameters, the shape of the current pulse provides additional information on the state of the watch.
In particular, faults can be detected in the mechanical part of the watch by comparing its
measurements to those of a watch of the same type in good condition.
Additional information about motor pulse analysis is available in chapter 16.5.
11.2
Procedure
-
Supply the watch with the Analyzer Q1 according to chapter 9.1
-
Select the
Graph of the motor pulse
function in the main menu
-
The time scale can be selected with the
RANGE
parameter according to the pulse width.
-
The measurement is usually performed with the nominal voltage corresponding to the battery
(1.55V for watches with a silver oxide battery). The voltage can be changed with the
VOLT
parameter, e.g. for testing the operation of the watch under reduced supply voltage.
