Swithing DIP switch #1 (D4) on: starts "dose mode" and keeps it displayed until the switch is not turned off (meaning no alternating displays - either immediate measurement display or running averages).
During the first minute, while the average for that minute is being calculated, uSv value is substituted with a word "wait".

Adjustable HV high voltage supply module for geiger tube counter and dosimeter
IMEX-38-56-1 is an adjustable high voltage generator module for Geiger-Müller
tubes.
The module is for use in geiger counters and dosimeters where portability,
small size, very low power consumption and stability is required.
Specifications:
Supply voltage range: 2.5-5.5V
High voltage range: 380 to 560V (adjustable with a 24 turn trimmer
potentiometer). Practically all popular western and russian-made Geiger-Müller
tubes are supported. Current limiting 4M7 resistor is already installed (for most
Geiger-Müller tubes of russian origin). Additional separate 0.125W 4.7M resistor
is provided with the module for tubes of western origin.
Low quiescent (standby) current: 0.5-10μA
Low ripple: 1 to 5V
Working temperatures: -20 to +60ºС
Three pin module: pin 1 HV, pin 2 GND, pin3 positive input voltage
Dimensions: 38.5mm x 7mm x 25mm
Module is encapsulated for isolation purpose in transparent epoxy.
