Verifying the temperature indication
To ensure that the results of the adjustment operations
described below are reliable, the following minimum
immersion depths should be maintained:
• 60 mm for bimetallic thermometers-types TS, TH, TM, TK
• 70, 120, 220 mm (ls+20) – according to bulb type –
for gas pressure thermometers (types TF, TG).
These lengths are indicated by a welding seam around
the bulb.
The reference temperature
If the temperature of the medium (liquid, gas) in which the
stem or the bulb is immersed is not known, and neither a
correctly calibrated reference thermometer is placed nearby, or
a calibration bath (filled with oil or water and stirred)
is available, the instrument can be verified by either of the
following two simple methods:
a. Immerse the thermometer stem or the bulb in melting ice
(ratio ice: water approx. 2:1) and stir it around. After about
5 minutes – the time to allow the measuring system to
stabilize – the thermometer should indicate 0°C.
b. Immerse the thermometer stem or the bulb in boiling
water. After about 5 minutes – the time to allow the
measuring system to stabilize – the thermometer should
indicate:
100 °C at 0 m (sea level)
99 °C at 327 m
98 °C at 654 m
The temperature of boiling water at other altitudes can be
found by assuming a drop of 1°C per 327 m height increase.
In this approximate but often useful method, temporary
atmospheric pressure variations can be neglected.
Important ! Verification and adjustment at ambient
temperature are not recommended.
Verifying, setting and readjusting Rüeger Thermometers
All these thermometers, designed to meet the most demanding requirements, are provided with one or several adjust-
ment devices. These devices allow :
• setting to a given working temperature, for accurate indication and the compensation of errors due to the
measuring point
• readjustment, for example after long use under severe vibrations or frequent shocks
• rotation of the dial (type TMH).
• resetting after rotating the dial (types TMV... and TMI...), for example to orient the stem in a different direction
• alignment of a thermometer mounted in a row
• setting switchpoints of electrical switching thermometers from the outside; types TM (H, V, I) K, TG (H, V, I) K,
TF (H, V) K
• external resetting of thermometers with pierced case; types TH (H, I)

Instruction manual for adjustment and recalibration of thermometers
A. ADJUSTMENT BY DIAL ROTATION, 360°
for thermometers in: thermo-MODUL Group, type TMH
a. Twist the bezel counter clockwise to release, and remove the glass
b . With the fingertip, and without pressing inwards, turn the dial
gently until the graduation corresponding to the true or re f e r ence tem-
p e r a t u r e is opposite the pointer
c. Fit the sealing gasket against the dial, replace the glass, and twist-
lock the bezel, hold the assembly
External adjustment (pierced glass), ± 360°
available for TMH group
a. Unscrew the plug on the fixed device. Important : this plug is a seal,
so the O-ring with it must not be lost !
b. By means of the setting key supplied, turn the adjustment screw to
the left or right, until the dial graduation corresponding to set-value
c. Screw the plug back in, not forgetting the O-ring
External adjustment, ± 10°, available for TH (H, I)
a. Remove plug from the back of the housing
b. Insert a small screw driver into the dial holes
c. Adjust dial until indicated temperature corresponds to set-value
d. Refit the plug firmly in the case
B. ADJUSTMENT BY POINTER REPOSITIONING,
360° for thermometers in: thermo-STANDARD Group,
types THH, THV, THI pierced glass
a. Remove the plug from the glass
b. Insert the setting tool (225-002)
c. Turn the grey ring (2) to bring the dogs onto the faces of the
pointer (4)
d. Turn the black knob (1) to engage the blade in the slots (3)
of the pointer (4)
e. Holding the black knob (1) stationary, turn the grey ring (2) until the
pointer indicates the temperature required
f. Take the tool out, replace the plug in the glass
C. ADJUSTMENT BY POINTER REPOSITIONING,
360° for thermometers in:
thermo–MODUL, types TM (V, I) and TG (H, V, I)
thermo–FLEXIBLE, types TF (H, V)
t h e r m o – K O N TA K T, types TM (H, V, I), TG (H, V, I)
and TF (H, V) K
a. Twist the bezel counter clockwise to release, and remove the glass
b. Engage black knob (1) in slots (3) of the pointer
c. Hold pointer (4) stationary with two fingers on sides
d. Turn knob (1) to set pointer
e. Refit the glass and bezel, not forgetting the dial/glass seal
• The tool N° 225-002 may also be used for this adjustment. The grey ring (2) can be taken off if desired, to simplify operations
• On thermometers of group TK, take care not to lift the pointer, as this could cause the drive pin to disengage from the plate.
Setting tool no code 225-002
1) Black knob with 2-tooth blade, for engaging in the slots (3)
of the pointer (4)
2) Grey ring with 2 dogs, for engaging in the faces of the pointer (4)
Setting tool no code 225-003
1) Black knob with 2-tooth blade, for engaging n the slots (3)
of the pointer (4)

seal, so the O-ring with it must not be lost!
b. By means of the setting key supplied, turn the adjustment screw
to the left or right, until the dial graduation corresponding to the
true or required temperature is opposite the pointer
c. While pressing the adjustement screw in, turn it to bring the metal
driver into dial with the switchpoint temperature required
d. Screw the plug back in, not forgetting to fit the O-ring
E. ADJUSTING THE SWITCHPOINTS ON ELECTRICAL
SWITCHING THERMOMETERS,
Group Thermo-MODUL, types TM (H,V,I) K and TG (H, V, I,) K
Group Thermo-FLEXIBLE, types TF (H, V) K
a. Unscrew the plug on the fixed device. Important: this plug is a seal, so the O-ring with it must not be lost !
b. By means of the setting key supplied, turn the adjustment screw to the left or right, to bring the metal driver near to the red
switchpoint indicator
c. While pressing the adjustement screw in, turn it to bring the metal driver into contact with the switchpoint temperature required
d. Turn the driver to a position where it does not hinder reading the temperature (e.g. on one of the dial tabs)
