2.2 Setting the Switches
2.2.1 Setting the Supply Voltage Selector Switch
Note: The H-25C comes with three different supply voltage specifications, 100/115 VAC, 100/200 VAC,
Or 120/240 VAC. The frequency can be either 50 or 60 Hz. Use the supply voltage selector switch
on the rear of the H-25C to select 100 and 115 V, 110 and 220 V, or 120 and 240V.
Set the supply voltage selector switch to the side labeled appropriate to the AC line voltage you
intend to use.
The H-25C Halogen Leak Detector will operate properly o AC power of voltage matching the
instrument specifications.
2.2.2 Setting the “GAS” (type of gas) Switch
Note: The “GAS” switch is at the right of the setup area on the main unit front. Open the setup area
cover to gain access to it.
Set the “GAS” switch lever to the “R134a” position if using the instrument for R134a leak detection, or
to the “R12” position if using the instrument for R12 leak detection.
Note: Can also be used to detect leaks of certain freons (R22) and freon substitutes (R502) in
addition to R12. If using the instrument to detect leaks of these substances, set the switch to the R12
position.
2.2.3 Setting the “UNIT” (unit selector) Switches
The measurement units to be used are set with the “UNIT” switches (1,2). Set the switches as
follows.
The unit that can be registered is either “X 10-5 std. ml/s” or “g/y”.
Note that the units for leak flow are to be selected from among “X10-5 std. ml/s”, “g/y”, and “oz/y”
Note: The selected units are indicated in the display area during measurement.
